I personally like the idea of individual posts. We've all got insanely sporadic schedules which make it hard to meet up. I work the night shift so when its not the weekend, I'm around in the afternoon (3pm pst-ish) until about 9pm when I start getting ready for work. After I get back, I'm pretty much dead to the world, so collab would have to happen in that 6 hour window. 

I'm by no means opposed to the idea of a collab, I just worry that it might delay the RP significantly more.
