I feel like I'm less likely to get suck and more likely to finish the initial writing quicker as there's someone cheerleading.

Yeah, me too! Some people have mentioned they'd be wary of cowriting because they have trouble finishing projects or are kinda on again off again writers, but I think it'd be easier to follow through if someone was depending on me.

I'd have trouble writing over IM! I tend to be slow. Well, actually, I tend to write in short bursts.

Thanks for the input!
