Do you have a Tumblr? If so, do you use it to post original content or are you a serial reblogger? If you don't have Tumblr... why the hell not? You have no idea what you're missing out on and I'm offended by your impertinence.
I don't have Tumblr. Just don't really see the point. Most of the time I see it just used for posting annoying GIFs and the like.
I have tumblr! Currently I just use it to post my art but I'm oh so close to giving up on that and using it to reblog stuff and just putting all my art in a tag. :x I lurk and like things and I check my dash obsessively. I love tumblr so much even if it took me like two or three years to figure out how the heck to use it.
I have a tumblr. Being someone who doesn't really care about fanart or looking at fandom gifs or screencaps to begin with, I gotta say I find tumblr less than pointless XD I'll check in once a month or so, reblog some picture of Yoshi that pops up and call it a day lol
I have a tumblr, I reblog things.. XD There was one thing that I created by myself though, it was to help promote the game Kya Dark Lineage.
Nope. I just have a twitter, and that's really all I need to communicate with those who need to get in touch with me(aside from MSN, of course). Like Geoff, I never really saw the point of tumblr. I search for gifs there, but really not much else. I will admit that I don't understand it much, either, but eh.
I have it, but I barely post on it. If I do, I either reblog, post something Yu-Gi-Oh related, Pokemon related, or a pic I like. Other than that, I just search tags and gifs.
I could never get into Tumblr. D: Between Facebook and Twitter and Livejournal, I think there are way too many social networking sites out there and I never got what Tumblr's gimmick was.
