Thank you for the link to Mananon's site! Looking at these numbers (the graph of LJ activity since 2000) is quite telling. I wasn't sure if there had been an actual, noticeable impact -- obviously fandom has decamped to DW in a major way, but it's always hard to tell if you're just judging things based on your own little corner. But, uh, yeah, their numbers are plummeting.
