I think that's a fairly accurate description^^ I only use Tumblr for sketching ideas and inspiration, nothing more than that. Mainly because I don't really know how to use it, and secondly because it's interface doesn't interest me that long to stick around and find out how to. I do like LJ a lot better, and I think the communities there are good. I also read a lot of fanfiction when I get the time, and used to find all my favorite authors on LJ
but lately this forum is becoming like my work place lol. I feel like I'm always on here ahaha
I agree, there's lots of good authors on LJ, but most of them can be found on FF.net too. Well, the reason I found LJ was because I was following an author on FF.net and I stalked her all the way to her LJ. LOL. I know what you mean, I was more active on Twitter, but lately I've been here a lot.
