Science fiction author Charles Stross has a private Livejournal site he uses for testing fiction -- or did:
I started out on Livejournal because, back in the day, it inherited a bunch of folks from SFFNet when SFFNet curled up and sort-of died; SFFNet in turn inherited the users of the Delphi SF forum from bulletin board days. It's all about the people, as usual, and Livejournal for many years was a social network hub for SF/F fans and authors. But Livejournal gradually lost out to Facebook in the anglophone world, just like MySpace. Unlike MySpace, LJ survived by becoming the social network of choice in Russia: a few years ago LJ was sold to a Russian company, and has gradually become a 90% Russophone social site with a weird bag of western SF fans still lurking in the moldering wreckage of what was once a thriving social networking system. There were periodic upsets because any major Russian political event would seemingly draw distributed denial of service attacks; a lot of people left, either decamping to Facebook, or to smaller specialized social hubs—the founders of Livejournal released their software under an open source license, and some folks are successfully running small-scale LJ servers with their own distinct communities.
I probably stuck with LJ for too long, because back in the day I paid for a perpetual premium account—unlimited access and no ads: the urge to get one's money's worth out of something you've paid for is hard to resist. But the rot has finally gone too far. This Tuesday Livejournal pushed out a revision to their terms of service that emphasize the service runs under Russian law, and specifically requires compliance with Russian law on minors -- which makes any discussion of "sexual deviancy" (aka LGBT issues) illegal or at least a violation of the ToS.
So I'm currently migrating my entire Livejournal presence to Dreamwidth, a service set up by some of LJ's original founders that focuses on providing a Livejournal-like set of services for creative types (and, significantly, is not subject to Russian law because it's not based in Russia).
Curious what effect this "Russian law" will have on Thomas Disch's LJ (still extant since he died but in memorial status). Possibly Stross is being alarmist and just looking for a reason to bail -- I haven't done any research to confirm his legal interpretation.
