eBay couldn't hold the nice run it had this past week and ended the week on a down note. Today ,eBay Inc. (NASDAQ: EBAY) shares shed $1.07 or 3.51% of their value to close at $29.39, unable to remain above the $30 mark reached yesterday.

The reason for today's sell-off could be attributed to some profit taking, but most likely it was caused by Cantor Fitzgerald initiating coverage on eBay with a Sell recommendation (then why bother, I say). As an aside, I must say that unlike many commentators here of late, I don't believe analysts' recommendations are governed by ulterior motives and politics. I'm of the firm belief that most analysts cover their companies impartially and try to do the best they can. Some are very good and very lucky, some not so much, in either department.

Okay, so back to Cantor Fitzgerald. The analyst, Derek Brown, said that he finds that core eBay has weakened significantly in the past years, with customers -- buyers and sellers -- moving to other ecommerce solutions as their behavior has changed. Brown set a price target at $25 for eBay's shares.

I haven't read Brown's report, so I'm not sure why he came to the conclusion he did. It would therefore be hard for me to disagree and yet, I do. I don't see it happening (despite eBay sellers promising me it is); I still think it is easier for people to go to one site where they can find everything in rather than to different other sites.

Finally, I'll just mention quickly that eBay Express was officially launched in the U.K. on Wednesday.

The big news today from eBay's analyst day was that Meg Whitman was promising: now, with even more revenue growth! Her presentation, and that of the other executives from eBay proper, PayPal and Skype, were really great. Evidently, either (a) you investors weren't watching or (b) without the analysts to tell you if it was good, you weren't ready to pull the trigger. After all, if a company talks to the analysts through market close, how can they affect the market? The stock was down a teeny bit, six cents, to $34.11, on a bit better-than-average volume.

Well. If you were online with me, you were armed with more info (you know, to toot my own horn, and all). I filled you in about eBay's view of their craigslist investment; how they planned to create synergies with Skype; how proud was the company of their 7% of worldwide long distance minutes; how PayPal will soon let you buy used books at your neighbor's yard sale with your mobile phone; and how $3 billion in cash was withdrawn from ATMs via PayPal debit cards. If I had to pick one thing I came away from those hours of watching Meg & team present (I mean, something substantial... I could go on forever about fashion choices but this isn't the style blog) it was that they really believe in their vision and they are fantastic at describing it. I was feeling a little scared off by the stock's rich price, but after listening to Meg, Bob, and the Skype and PayPal execs tell me about how they're going to change the world? Boy do I want to be along for the ride.

Why did eBay take a stake in craigslist, the everyman's online classifieds? It made sense to me immediately, although I don't think I could put it in dollars and cents: for me and my friends, craigslist is IT (and, it turns out, we didn't find this particular IT on eBay). I got my job, my friends, my gossip, my double stroller, and someone to pick up my beat-up dryer on craigslist. It's how we all connected locally - and it's not nearly so efficient to buy or sell a large but relatively low-value item (hello appliances & baby goods) on eBay.

Meg answers an analyst question about craigslist by saying this: "We say - increasing returns on a city-by-city basis with craigslist. It's the theory that the buyers go where the sellers are, and the sellers go where the buyers are; we see it as, where classifieds get to a critical mass." Translated to say: newspaper classifieds are so over but it wasn't eBay which demolished them: it was craigslist. My question is, how do you monetize that? I suppose time will tell. I'd hate to see craigslist start charging for listing garage sale announcements and, yep, those beat-up old washers and dryers. Meg says that eBay will allow craigslist to remain autonomous (and, one would hope, still free but for job listings). We shall see.

Skypecasts and Skype Me! are the names of the game: the answer to "how will eBay integrate Skype with PayPal and auctions?"

Everyone wants to hear more from our favorite CEO, Meg Whitman, and she has taken back the stage after lunch. She discusses the integration between Skype and eBay, raves about Skypecasts, and tells the gathered analysts: eBay transactions that allow potential buyers to "Skype Me" sell for twice the sales price of the transactions, that don't. Her keynote address is that "eBay provides your online reputation, PayPal provides your wallet, and Skype provides your online presence." She makes the argument that you will soon be able to take all of these aspects of your "self" with you wherever you go; "the internet will no longer be just a destination, but the fully integrated and ever present part of your lives."

[Tim Beyers from Motley Fool agrees with Meg: in his opinion, Skypecasts are a fantastic justification for Skype's $2.6 billion purchase price.]

According to Skype President Rajiv Dutta, over 7% of worldwide long distance minutes are over Skype. That's truly incredible. Skype is such a young company, too, and far more penetrated in Northern Europe than anywhere else (it was founded in Great Britain). The possibility for growth seems fairly huge. Will it justify the $2.6 billion acquisition cost? More on that, later, as we talk integration. What it will do is give some hope to the people who wonder at the eye-popping richness of a 50x P/E ratio.

I want to just focus on the numbers but Skype is about "conversations," as the execs are telling us, so I'll describe the entirely adorable presentation introduction, in which a middle-aged man somewhere in England talks to his mom over Skype. She's still in her bathrobe. Oh. My. God. I fall over from the cuteness and spend several minutes under my desk.

[Disclaimer: I own a few shares of eBay, and I am responsible for some tiny fraction of those long distance minutes talked on Skype.]

"I'll pay you back next time." How many times have you heard that? PayPal wants to change all that by allowing person-to-person payments via your mobile phone. If you are a PayPal executive and you're buying a case of wine in Napa Valley, no need to tote a bunch of cash -- just let your friend pick up the case on his credit card and you can PayPal him back a couple of bills in the parking lot (before putting the half-case in the trunk of your Mercedes sedan, of course). I'm psyched, because next time I go to the Goodwill outlet, and my friend Larissa and I go diving for funky thrift items to re-sell on eBay, we can combine our loot (it's less per pound the more you buy) and I can pay her back instantaneously. Or how 'bout this: garage sales! It's brilliant. If I could use my PayPal account at garage sales, I'd buy so much more.

This is working now, and a new feature that was just released: text-to-pay. There's a demonstration of how it works; the presenter buys a Walk The Line DVD from his phone with his PayPal account (a UPS deliveryman brings it immediately -- yeah, you're cute, eBay). It's great, but you could already buy that DVD with your cell phone (yeah, you had to call the 800 number and tell them your credit card number, etc. - but still. Not changing the world). You can't use your credit card at a garage sale. Your buddy doesn't have a credit card acceptor when you split the check. That's where PayPal makes a difference, in my opinion.

eBay is really three brands now: eBay, Skype and PayPal. The PayPal team is on now, and after an introduction by a hugely pregnant woman whose presentation was excellent (but I was in such admiration of her belly that I had a hard time focusing), we got some numbers. This one was interesting to me: $3 billion has been withdrawn using PayPal debit cards.

I have a PayPal debit card, and I can't tell you how nice it was to be able to use funds from eBay sales instantaneously (to buy coffee at Starbucks, naturally). This figure really illustrates how widely the PayPal service has penetrated the interperson payment marketplace.
