At dreamwidth I'm sobota as well.
I've transferred my livejournal over there too. I'm just about as active over there as over here (read: not really at all) but it's a good a place as any to store my 16 years worth of drivel.
At Twitter, I'm at two places: @snuggledeath and @sdmwrites.
I am super active on both of these; @snuggledeath is private and @sdmwrites is public and super political.
At Tumblr, I'm mazeballet. I post a lot of weird stuff. I'm trying to become a studyblr because I got accepted into my Master's programme. [#humblebrag]
At Instagram, I'm themazeballet. I haven't posted since my birthday, but I'm not a very exciting person. There's a link to my blog there, but there's not much there at the mo'.
So there you have it; if you want more private things like Snapchat and my Facebook, I'm willing to send you those on an ask basis--just ask and I'll give them to you.
