Depends on the type of popularity you want.
The games section (and sadly the random discussion)
are pretty much filled with spammy posts and
play. If you start posting in there, you will become
a part of the game, and be mentioned more and
more.
If you just spam indiscriminately, as I do,
you tend to just annoy people.
Whoops! Didn't think about that. Don't worry, though. Someone already guessed my real name and now it's Kilroy's turn. If I could edit the title of the forum, I would. I mean, I don't really want to annoy people. Maybe I'm just trying to get a little more noticed without offending people, annoying people, or create ideas that these people don't like.
