I like Yahoo 360 for a lot of the same reasons I like my.yahoo. If you’re already using Yahoo services for photos, etc. it’s an easy way to share things with your friends and acquaintances. I don’t know how much it’ll appeal to the blogging community since there doesn’t currently seem to be as much room for customizing the appearance either via skinning or layout customizations.
The integration with local restaurant reviews is fantastic. There’s notes about Yahoo Groups integration, but it doesn’t seem to be working for me right now.
If anyone wants an invite to check it out leave a comment here and I’ll send you an invite.
