Why do you need so much info on Mike? Can’t you just evaluate his statements/work on its own merit? The whole point of open source, federated platforms is that you don’t have to trust him. If he decides to enshittify it, you can just go with a fork or another instance. A nomadic identity isn’t a centralized alternative to the fediverse, it’s just a way of bringing some of the features of a centralized identity to a decentralized one (at least, that’s the way I interpreted the article).
I don’t know about the UK, but my experience in the US was exclusively women in elementary school, 80-90% women in middle school, 60-70% women in high school. I was actually surprised when I first had a male teacher in middle school, I guess I had thought that male teachers was like an old timey / TV / college thing.
