I just use tumblr for rebloging gifs and pics, I'm old and can't cope with anything else *g* I find it so confusing trying to follow discussion there because I click a link with a comment and it'll just take me back to the posters main blog or something, there's never an easy way of following the discussion! I found it bizarre that fandom prefers tumblr over LJ, but oh well. I like it for pics, but that's about it. For episode reviews and meta it's LJ for me every time
