I'm going to repeat what I said previously: I've noticed that, if people crosspost both here and dreamwidth, I've yet to see anyone get more comments at DW. (A lot of people seem to get virtually no comments over there, but a lot over here...) If part of the issue is activity, I think it has more to do with people being busy/burnout/etc. This game took place during a time when many had school (i.e. Game 2 didn't have that problem, for the most part), holiday plans, etc. In my specific case, I know I wasn't as active because I was tired after Game 2 and all FF'ed out for awhile, but I think I'm finally over that.

I also imagine people who don't have DW accounts at the moment may not want to move over there for just one community, especially if they don't participate much (but do sometimes), they may just never rejoin. I know I never even check my DW account and am often too lazy to even log on there when I have other sites to check, so I imagine that I'd... participate even less if it gets moved.
