Home invasion - Mastodon's Eternal September begins

The fediverse is dealing with a huge wave of Twitter people bringing toxic ideas with them.

@micahflee much appreciated. I’ve never cared about clout, going viral, etc. I’ve had under 2k followers on Twitter since I joined in. 2009. What I care about is finding connections. I want to find people to learn from, to make space for and hear their stories. I’m Gen X who has always felt out of place and it feels like things are changing and making sense as my generation and older fight against this much needed progress. I just want to be where that is.
