My experience so far here is not terribly different from Twitter, to be honest. I'm here because most of the people I care about moved. But a substantial fraction of my mentions are people interpreting my every word as uncharitably as possible and telling me what an awful person I must be.
When blocking them gets too exhausting, I'll probably just drop off, and you'll have to tell me how awful I am via email or USPS. In person by appointment only,
