For the last few days, I have been playing around with Yahoo's new 360 blog / social community. I can see the potential that it could eventually have. However, I don't think it is quite ready for prime time. Granted, it is in beta now, so a lot of leeway can be given. A big part of the blogging experience is personalization and that is something that is currently lacking in 360. You cannot yet even change the color scheme, much less any of the design elements. I assume that will come in time. Still, the myriad of features that it currently offers, and those to come, makes this a definite possibility for a killer app. Keep up the good work, Yahoo!
