I realised something, well 2 somethings actually.
1. I didn't miss it.
2. When I did visit Tumblr I undoubtedly felt worse when I logged off than when I logged on.
Tumblr is toxic - that's the only conclusion I can come to. Some of the posts are lovely, but there are always, and I mean always, the ones that make me want to reach through the screen and strangle someone. The tension on that site is unbelievable.
I miss the LJ days when people were (mostly) civil to each other and if you didn't like something you mostly buggered off rather than try and get everyone else to dog pile some poor person. Of course it didn't always work that way, but LJ has always felt much more civilised.
