Not unless I'm looking at doing something similar and want to get some inspiration or help figuring out what to put in the op. I looked at a couple of homestuck rps today as well as one other but I don't remember the name of it. But I didn't read too much into any of them.
I have before, I don't usually make a habit out of doing so though. I remember that way back I did read an Arcana RP and a pokemon RP about getting shipwrecked that were both just really good to read. I also was reading echo; a Kanto Journey before someone dropped out and I was able to join.
Those were all a long time ago though, I read other RPs far less now since I'm generally quite busy and have plenty RPs I'm in to focus on.
