I've basically lost all contact with my online world since leaving twitter. Nobody is around anywhere else. It's a lot harder to find someone active to follow here.
People seem to have stopped using hashtags, so searching for them is almost useless now. If I could just see the followers and followees of other users, I'd be much easier, but it's all fragmented and obscure.
Having social anxiety, my online world has kind of been the only source of social interaction I've had outside of work the last... 20 years, and poof, it's gone.
Yet I still can't go back to that place. I just can't support what it has become.
