I’ve given Yahoo! 360° a bit of a spin (damn, am I witty or what?) and so far it looks interesting. To fill in my lists of stuff (movies, books, music, etc.) I just copied and pasted my stuff from Friendster, and that worked pretty well. (Insert rant here about some open data format like FOAF so I could just point these things at a URL to fill in my data…)
My guess (I know, I’m so full of “insider info”) is that things are only gonna get better. I’m basing this off of seeing “Coming soon! Share your blog, photos and other RSS-enabled content on your Yahoo! 360° page.” which I’m hoping can make Yahoo! 360° into an uber-aggregator of sorts, but can they pull it off? Who knows?
Anyway, I’ve so far not had any problems, and so far can’t really rave about it. I’m going to reserve judgement until I get to kick the tires a bit more.
(Oh, if you happen to know me, and want an invite, let me know.)
