building an active blgo community?
 

what sort of things help to develope a more active community on a blog? what gets comments, bookmarkers, forum posters, and active members coming to a blog? polls, games, contests, chat, forums? what works for you?

regarding forums:
i create a lot of different users and post with them all by myself for some time and then buy traffic (lots of traffic) and from that point on it just grows by itself.

Don't buy traffic for a forum. Use other forums to advertise in your niche area.
