I tend to restrict myself to a maximum of two active 1x1 threads. For example, I've got two going right now but they are for fully fleshed out, vastly different rps. I understand the frustration though. Especially when there are people who might not be getting attention, because someone with 3-4 interest checks is bumping them all at once. I prefer one or two devoted ideas to build on, while other people prefer the shotgun method.
