Oh yeah, that's what I've been trying to do. It's also worth looking into participating in some challenges (for me), the other day I've made my first post on #metalweekend and it was a really fun experience.
Also, I just don't think it looks too good when new people join and the first thing they're confronted with, are all the artificially upvoted posts.
Contests and challenges are a great way to get involved. I think there's something out there for everyone.
