I think Jossverse is a great idea, with it explicitly being devoted to non-Buffyverse, non-Serenityverse, non-comics Joss media -- so Dr. Horrible fits alongside Dollhouse and any other side projects that come down the pike, until such time as one series is a big breakout hit that deserves its own complete thread.
This to me strikes a middle road between too many limited-interest threads, and giving an easily-identified specific place for discussion about these projects to take place.
I really LIKE this suggestion and will definitely vote for it should I get the chance.
I too like the idea of a Jossverse thread way more than a dedicated Dollhouse thread, at least for now.
I very much like the idea of an "other lands in Joss's head" thread.
Of course, then I worry about "What if Joss and Tim do a show together? Which thread does it go in?"
Would it be Jossverse or Whedonverse? It's not the Timverse thread.
We can have them arm-wrestle for the honor.
Would it be Jossverse or Whedonverse?
We've always called it Jossverse.
And I second the arm-wrestling idea for a Joss/Tim show. The show shouldn't get an auto-thread, but any such trial by combat should!
I thought I had heard Whedonverse more often. Google agrees with me, 91,100 to 33,700.
Yeah, but not around here.
Also there is already Whedonesque out there.
