That's a very subjective question. You can make your OOC section sparkle and market the hell out of it, but it will still come down to the individual. Much like my digital photography, I can have them on display for what seems like forever, until that "right" person comes for that particular piece. The same applies to roleplay. Another thing to understand, is that a low percentage of roleplays have a significantly long shelf life. Check out those guides and make the roleplay that interests you, and the rest is up to the population.
