Gregory's Server@nixCraft I stopped contributing after the Monica scandal. The new owners were happy to make an example of someone for a pre-crime just to promote woke ideals to new investors.
I have published some personal stuff on SubStack which is a more or less trustworthy blogging site, some people with a following gain money in subscriptions.
I also have answered a few questions at CoDidact, a competitor to StackExchange that is more user owned, if everyone registered an account there it would make SE redundant. You can even ask and answer questions there that you had popular answers to and copy your own answers over if you want to help populate. NOt as many substacks but a selection of the more popular ones.
