Twitter calls Google (GOOG) a "good role model," but says it isn't ready to rush down the road to advertising.

Nonetheless, an ad-based revenue model is something that cofounder Biz Stone says they "will be looking to do down the line." But, for now, he continues, Twitter is focused on "creating value for our users." For now, revenue generation ideas are being put on paper, "and we're definitely going to get to them," Stone says.

Here are some highlights from this past week's earnings coverage on BloggingStocks:

• Ann Taylor Stores Corp. (ANN) declining same-store sales offset better-than-expected Q3 earnings.
• Canadian Solar Inc. (CSIQ) reached a new 52-week high after Q3 results handily exceeded expectations.
• Dillard's Inc. (DDS) said that it swung to a Q3 profit due to cost cutting as revenue declined year over year.
• GameStop Corp. (GME) reported uninspiring Q3 numbers that included a slump in same-store sales.
• Home Depot Inc. (HD) lower Q3 earnings and revenue beat analysts' estimates, but shares still declined.

After previously announcing that he would leave the CEO post in December, Bank of America (BAC) head Ken Lewis is backpedaling in light of the company's difficulty in finding a replacement.

The Wall Street Journal (subscription required) reports that Mr. Lewis "has said he would consider postponing his retirement if directors need more time to find a successor or smooth the transition to the next CEO, according to a person close to him."

Take the Nook off your Christmas list. The new e-reader from Barnes & Noble (BKS) has already sold out, and more won't be available until after the holiday has passed. The next batch will be available, at best, by November 4, 2010.

In a statement, the company said, "While we increased production based on the high consumer interest, we've sold out of our initial Nook allotment available for delivery before the holidays." If you still want to give the device as a holiday gift, Barnes & Noble will give you a gift certificate to tide the recipient over until the device itself comes around.

TransCanada Corp.'s (TRP) shares, first recommended on May 11, 2009, at a price of $26.56, have pulled back, and the dip represents a buy opportunity, which is why I'm reiterating my buy rating for the stock.

TransCanada is natural gas play with promise: it's a natural gas transmission and storage company that also owns oil assets and electric power generation assets (including 19 wholly-owned power plants). A solid $1.45 annual dividend adds to the positive story.

Google (GOOG) is letting a few developers peek behind the curtain. The early look the company's new operating system, Chrome, is happening in true Google style: by invitation only. When it's released, which should be in time for the holidays, developers will be able to bang away at an open source solution, tapping an army of volunteers who are eager to work for bragging rights.

The open source version is called Chromium OS, which will hit the market a year before the "consumer" version is ready, which is how Google will be able to tap the wisdom of developers around the world. In a blog entry, Google explained, "This means the code is free, accessible to anyone and open for contributions." The project includes the code base, user interface experiments and some preliminary designs, all of which can be used for ongoing development efforts. To energize the potential base of contributors, Google said that "development will be done in the open from this point on."

Here are some highlights from this past week's earnings coverage on BloggingStocks:

• ADC Telecommunications Inc. (ADCT) posted a surprise net loss for Q4 and predicted a loss in Q1.
• BJ's Wholesale Club Inc. (BJ) shares fell after Q3 earnings met expectations and offered guidance for FY.
• Dell Inc. (DELL) posted lower-than-expected Q3 earnings, prompting a sell-off of shares.
• Foot Locker Inc. (FL) said Q3 earnings slumped more than analysts' forecast, sending shares lower.
• Gap Inc. (GPS) reported growth of EPS and revenue in Q3 and announced a share buyback program.

The rally in gold just doesn't want to quit. You are probably wondering what is going on. Central banks around the world hold gold reserves. Periodically, they buy or sell gold, depending on how they view world markets. Right now, central banks are net buyers, the first time since 1988.

A weak US dollar is the main stimulus for central bankers' gold purchases. India just bought 200 metric tons from the International Monetary Fund. Central bankers in Mexico, Russia, the Philippines, all have increased their gold purchases.

European Central Bank President Jean-Claude Trichet jolted the markets Friday with the announcement that the ECB will gradually withdraw the emergency cash injections it has added to the financial system, in order to prevent an acceleration in inflation.

"Not all our liquidity measures will be needed to the same extent as in the past," Trichet said at a conference in Frankfurt Friday, Bloomberg News reported. "Any non-standard measure whose continuation would pose a threat to the achievement of price stability must be undone promptly and unequivocally."

I was wrong about Ann Taylor Stores Corp. (ANN). Thought it might make a possible earnings trade. Well, Q3 earnings are out, and it looks like the market has given a thumbs down to my thesis. At the time of this writing, shares were off by almost 4%.

It's funny, because Ann Taylor has done so well in 2009 as a stock that one could have supposed that a wide earnings beat would serve as a catalyst for capital appreciation. The retailer made 20 cents per share on an adjusted basis. According to my earnings preview, 6 cents was the analyst number. I mean, come on, that's an example of solid performance, correct?

In the past, I've covered Rochdale Securities analyst Dick Bove's inane ramblings about how fantastically awesome Bank of America (NYSE: BAC) CEO Ken Lewis is. Last month he called Mr. Lewis "phenomenally good" and his notes to investors are beginning to have more in common with 12-year old girls' Valentines to Zac Efron than conventional research.

But he has outdone himself this time. While Bank of America's chairman of the board goes on a cruise instead of devoting all his energy to finding a successor, Mr. Bove has found the solution to replacing Ken Lewis: "In sum, Mr. Lewis was a key architect in the creation and management of Bank of America. He knows this company better than anyone else and he knows how to operate it," Bove wrote in a research note issued this morning. "At this point in the company's history, this is the type of leader needed. Convincing him to return would be the biggest morale builder that management could get."

We've put three quarters behind us in 2009, and the most recent one was merely another miserable step downward for the beleaguered newspaper industry. Total ad revenue plummeted in the third quarter to $6.4 billion for the print jockeys, a decline of 28%. This info from the Newspaper Association of America drives home the notion that conditions will only worsen for the newspaper industry. So, if you're hoping those shares of New York Times Company (NYT), Gannett (GCI) and Washington Post Company (WPO), holding your breath will leave you little more than dizzy.

Of the total advertising revenue generated in the third quarter of 2009, $5.8 million came from print, the lowest quarterly amount this year. The $623 million in online advertising sold by America's newspapers was also 2009's worst. Both are down substantially from the same quarter in 2008, when the newspapers posted print ad revenue of $8.2 million and online ad revenue of $750 million, according to NAA data. At this time last year, we lamented year-over-year declines approaching 20%. Now, we have the same feelings as ad revenue drops approach 30%.

What is the Philly/Fed Index and why is it important? The Philly/Fed Index measures manufacturing activity in the Philadelphia area. While it measures only one area of the country, over the years it has been a leading index for manufacturing overall.

Why bother measuring the manufacturing sector? The main reason is that manufacturing accounts for 12% of our GDP. Growth in manufacturing indicates that orders are picking up. If orders are picking up, the next step is to hire more workers. Hiring more workers speeds the growth of our economy and at the same time puts unemployed persons back to work.

Today was a very unusual day. There was no real economic data to absorb. And the markets did see some unusual options trading ahead of expiration date at 4:00 PM today. Disappointing earnings kept a negative bias in the air despite a brief recovery into positive territory in the final hour today... Yet the negative close seemed almost a certain fate today.

Here are today's unofficial closing bell levels:

Dow 10,318.16 -14.28 (-0.14%)
S&P 500 1,091.37 -3.53 (-0.32%)
Nasdaq 2,146.04 -10.78 (-0.50%)

If, in fact, jobless claims have peaked, that's good news for payroll services specialist Automatic Data Processing (ADP), and that's one reason I'm reiterating my buy rating for the company's shares, first recommended on June 22, 2009 at a price of $36.84. If you bought ADP in June, you're up about 20%.

Despite the worst recession in more than 25 years – one that has devastated payrolls – ADP has held its own, with its stock price this year recovering about one-half its loss following the drop from its peak in 2007.
