http://360.Yahoo.comAt the time of this writing, the new service from Yahoo! is in testing and the only way to become a member is by someone inviting you. You may visit my site at:
http://rockymoore.com/articles/287.aspx to leave a comment with your email so that I may invite you to check out the new Yahoo! system.
Anyway, their new service is more of a personal data center than just blogging. While it is Yahoo!'s first entrance into the blogging world, it is very weak on blogging and has little you can do to customize your blog, it will look pretty much like every elses blog.
They do have features beyond blogging though, such as sharing music (rather limited) and photography gallery for your pictures.
There is a strong "Friendstr" style to the system where you have contacts to "your" friends and they have connections to theirs and so on and so on.
If you want to give it a spin, drop me a note.
