ENGLISHTIPS_blogs AND/OR SOCIAL NETWORK FEATURES?

Well, here we go.
I need your opinion on whether we need (or how badly we do ) the following features at Englishtips:

BLOGS (every user gets a blog hosted at Englishtips where s/he can blog )
Dangers: Can become a mess or tricky in the long run, as users may want to start sharing links at their own blogs instead of ET :)

SOCIAL NETWORK (registered users can create/join groups, become friends with each other, comment in each other's profiles, etc etc)
Sounds very interesting for me, as this can help us build even stronger communities grouped by common interest.
Note: at the moment both features, though located at Englishtips, will probably require separate authentication (registration).

PLEASE VOTE ABOVE AND LEAVE A MESSAGE IN THE COMMENTS (BOTH RUSSIAN AND ENGLISH ARE WELCOME!
