Yahoo! Mash?

Although I read about this a few day ago, I'm still flabbergasted that Yahoo! has created a social networking site, Yahoo! Mash. According to the review by Download Squad, Yahoo! Mash has similar features to MySpace and Facebook. They will even be opening up a 3rd party development platform (like Facebook did) in the next few months.
One interesting note from the review...friends can start pages for each other to invite them to join the service.

But still, does the web really need another social networking site?

What we need (and I have read about) is a social networking site to combine social networking sites....
