Hello!
Hmm, well... I believe the famous people here are known for being either extremely nice and funny, taking up staff duties or being an artist. Ohh! Huge avatars and signatures are also a must... Don't forget all those gifs and a huge profile page to keep them viewers coming.
Either way, popularity shouldn't be a priority in these forums. If you pay attention to the quality of your posts you'll get noticed soon enough. It's always better to have a few amazing friends than have hundreds of people stalking your profile. But then again, all that power does sound tempting...
