So I was wondering, are there people out there that enjoy reading role plays without ever participating? Or even making their presence known to the RP members? Or is that the only readers of an RP is its own players? 

I personally keep at least one RP to follow and read for every 10 RP I participate in. I know, lots of RPs, I just admire writing instead of TV. Anyone out there actually READ other people's RPs and follow them?
