Sherlock fandom where are you?

[mekare]

Help! I watched season 4. Where on earth is the conversation about that going on? Considering the membership of this comm, I'd assumed there'd be a post, an acknowledgement, anything.
Where are the people who I can talk to about it? Where are the reviews of episodes, rants, analyses, screencaps?

Basically, I've been out of the fandom for a while and don't know where everyone's wandered off to. Where are you guys? Is EVERYTHING on tumblr only these days?
