The community is still technically there, but teahound in a bout of table-flipping nuked all the comments (i.e., where 85% of all the content actually is). Along with LJ in general, the community has been in something of a decline in the last few years and this seals the deal.
FD2 was home to some useful discussion, but the closed "treehouse" nature of the place worked both for and against it. Either way, that discussion is likely gone forever - the loss of the community means that some significant, primary-source info on important events like 12/16 is now gone.
