Because RGF has more members, they also have more intelligent posters. Sure, most the board is people talking about drugs and saying "fuck tha police" in every thread where someone talks about getting arrested, but it's really no different than it is here. There are still intelligent posters on that board and it's easy to avoid the dumb ones by switching sections, but here, no one goes anywhere else but Our Block, or atleast the bulk of the posts are made here, and it gets filled with random shit like "I'm drunk" "I love tits" "I love men, am I gay?" " This is so cool" (when really, it isn't) "I am drunk...again" "I am now high" "I am high again" "I love getting high."
You compare it to RGF, and I just have as well, and the funny thing is, they still have more members.
