There's already been a split like that in Pros lj generally, and I think it's a shame. Spoiler issue aside for a second, I am a little puzzled by this and I'm wondering why you see it as a 'spilt' and not a 'blossoming'.

I remember when I first found Pros on lj, I think the_safehouse was *the* posting comm for all things Pros. Then you and others set up the wonderful discoveredinalj (still responsible for about half my output:-), and also ci5hq. Now we also have, for example, the recently set up teaandswissroll and ci5_boxoftricks for the Big Bang.

I'm actually chuffed to bits that our relatively small fandom is still so active, ever-changing, and evolving here on LJ.

I guess I'm just curious as to where you see a split, and why.
