Well I find it both a good and bad thing.
I'm glad our /rp/ is not as built up as Ponychans /rp/. It has various ongoing RP threads with lots of activities on them and they've been around for years, it's like various guilds. There are a few independant RPs on Ponychans /rp/ but they usually fizzle out since most of the attention is to the big ones.
Our /rp/ does indeed lack traffic which makes most of the RPs here lack activity, but I'm glad our /rp/ is not as build up as Pnychans.
Plus some RP game masters find it easier to manage a small group or work than it is to manage lots of players.
I remember an RP series I once did on Ponychan ages a go consist of Epic Mount lounging in a pool in Everfree Forest while other RPers, regardless of their history with me or not, could simply come and go, join me in the water and just RP-talk about stuff.
