I bet your brain is hurting! It sounds like you have taken in more in a month than my poor little brain could handle in a year! lol... It is fun to learn though. I have been here about two months and I'm trying to learn how to do everything. I don't have as much good content as you do, i'm mainly here to post my comic, but I try to throw other post in there as well.
It's a really cool community here (Once you make your way through the SPAM) and I've enjoyed it quite a bit.
There is a lot of good advice above! i agree with avoiding those upvote 4 upvote groups. I joined one hoping to see something of quality, it was just people posting their links everywhere. I even made a comment about how bad it was to see those links in comments that had nothing to do with the original post, and people STILL posting their link as a random response to that post. lol.. stay far away from those.
