I think it's funny, we're at complete opposites on the advantage of Twitter and Tumblr. I've got one flistie on LJ who occasionally posts links without it being obvious why. We share some fandoms, but not others, so whenever I see a non-descriptive link, my first reaction is... tell me something so I know if I care!

Though maybe the Twitter and Tumblr people at least mention the fandom? If my flistie doesn't mention the fandom, I just don't click any more.
