It does, but the problem is the positive dynamics of doing actual socialising isn't readily apparent.

Another problem is the spread of voting power and the limits of the current system. Unless new people get some more voting power within first couple of weeks the situation won't change. That is the idea about #spreadthepower. If you are an active user, if you do post meaningful and interest stuff, if you get involved, there needs to be some incentive not in the current form, but with increasing SP. Currently the visibility for the stuff by new users is low and sheer ammount of noise to content, to current SP holders it is not viable. There is also a thibg with UX. Hopefully the changes will come soon enough. But, the userbase is better do their part also.
