It's just so much easier to post stuff there and to share photos and links to cool stuff including fanfic recs. Not so much for long newsy, thinky things but I haven't really been in the mood to do those in a while.The biggest drawback is that it's harder to have any kind of involved back and forth public discussion but there's always email and the Ask Box there.
Maybe that'll change. Maybe Tumblr will continue it's recent drive to make itself harder to use. Maybe I'll start posting here again some day. Until then you can add Tumblr blogs to feed aggregators like Feedly if you don't have a Tumblr account and want to continue to follow me.
See you around.
