I think it has more to do with wanting instant gratification and signing up for more and more roleplays until we always have something to write for, which of course gets really tiresome really quickly and then people drop out.
This is the Guild in a nutshell.
That's probably the truest statement I've seen regarding why people join so many rps. Also, totally love how you, as you just put it, summed up the guild.
As to your additional question, I admit that it's partly due to me preferring to try out different genres - till now I don't exactly have a particular type of genre that I feel I'm best in. The other reason was probably my writing style? While in the past I would give free and casual RPs a shot, nowadays I won't do anything lower than advanced.
I think a lot, if not all, of us were at that level at the get go(free and low casual). I mean, everyone has to start somewhere, right? I mean, not everyone was able to write a chapter at the start. If they were, then it probably wasn't literate. In fact, I'm pretty confident that it was run-ons after run-ons. Of course, the more experience we get as writers by roleplaying, I think the we're able to grasp the essence of writing in a literate way(proper sentence structure, knowing when to use periods, commas, colons, and etc..). I think the same could be applied to touching different genres. We all probably at least attempt different genres to make ourselves well-versed in as many genres as we can. Perhaps getting to a point where we can write for anything(so longs the muse allows us to).
37.... Back when I was younger, got sick and was pretty much bed ridden for a while. So I helped admin an Rp forum, hosted my own And helped on three others. It's all I did to pass the time until I was well, lol
Now I try to limit myself to 2 1x1 and 5 groups.
37..? o_o Wow, that's definitely a lot. I mean, that's nowhere close to any amount of rps I have been in at the same time within a year. You definitely went IN for that. All I can say to that is it's mighty impressive.
