Yahoo has released Yahoo! Mash in what appears to be the closest thing to a Facebook-MySpace clone that I've seen coming from Yahoo. Initial impressions seem to indicate that it's not much different than Facebook at all and many individuals are happier using the older social network.
The site, which began an invitation only preview Friday, is quite an homage to Facebook, but it adds one significant new wrinkle: users can edit each other’s profiles, redecorating, changing information, and adding features. Think the Wikipedia version of a social network.
Of course, not all users are enthusiastic about this feature. Would you want to find your profile altered in a bad way by friends (or enemies?) I wouldn't think so. I do have a Mash Pet on my profile though, and I see that my friends are taking good care of him. (Please continue to do so.)
But others think that this is a plus, because you'll only be adding true friends, not people who would blatantly edit your profile. Also, some elements of other users' profiles cannot be altered (I tried. No luck).
For those who don't have access yet, here's a preview of my profile.
