AboutUs snags $5 million

While Wikipedia is clearly the dominant wiki on the web, there are some other worthy contenders. Just look at AboutUs. Basically, the site allows users to write up profiles on interesting websites (although, I couldn't locate BloggingStocks.com in its index). Currently, there are about 12 million pages.

It's a simple idea – but it's getting traction, with about 7 million unique visitors and 12 million page views per month.

In fact, the company recently raised $5 million. The lead investor is Voyager Capital.

Something else that's critical: AboutUs is generating profits. Yes, that's an oddity in the Web 2.0 world – especially since the website relies heavily on advertising revenues.

Then again, AboutUs has a stellar team. One of the most notable members is Ward Cunningham, who is the pioneer of wikis.

And, according to the AboutUs blog: "The Series A funding allows us to continue to grow and you along with us. We're excited about the possibilities for the future and can't wait for you to join us. Even now, we've got a number of things brewing at 'AboutUs Labs' that will knock your socks off."
