Sofurry and f-list are the best examples!
It's the most important, planned feature to me! Sofurry allowed everyone to create groups. That leaded to plenty groups of the same theme/topic but the idea itself is great! It's neat to form local groups and it made the difference for me as a writer that also writes in his native tongue.
Also a neat way to build groups focussed on a specific topic or theme of content! Group creation should be moderated like on f-list though.
I'm looking forward to thiss! Don't feel rushed but i would like to know when it comes!^^
