AddThis is "social media spam facilitation;" it helps your users add you to all kinds of social bookmark sites without leaving your page.
CommentLuv lets you remove the rel="nofollow" attribute for people who've posted more than a certain number of comments ... when they post it reads their RSS feed and pulls out a link to their latest post. That would be to encourage people to leave helpful comments on your site ... whether it works or not is an open question.
BlogRush seems to be popular. I haven't tried it myself, so I can't tell you much about that one. Same with My Blog Log.
Like James said, there are too many to count. What are you looking for?
Nothing specifially im just new to wordpress, i had a look thru the plugins but i couldnt find anything useful, so i wondered what people from here used, thought it might be easier to ask, rather than stuble thru 100s of plugins lol !
One more I'd consider looking at is the vBulletin-WP bridge, since you have some chat forums, just to integrate users, posts, etc. (Although this one is not installed the same as the other ones, you install it to vBulletin first): http://www.vbulletin.org/forum/showthread.php?t=134521
