Certainly, more activity in here would be welcomed from me, even if it's that muslim guy that everyone argues with (Gives a reason for people to talk on here). As far as attracting people on here, most that I know how to do is make posts and talk with people.
Which I think is important to maintain some level of activity on here so people don't forget that it exists. If we only have a post a week, then some people might just be "Nothing ever goes on in there, I'll check it in a while" then they might just forget to check it again. But if things are constantly changing and there's new posts/replies, it gives people the incentive to check it more frequently since there's always something new to look at.
I'll make it my mission to post on here at least once every two or three days, even if its just to share some news or a meme or something.
