I have stopped asking questions there. The moderation is so heavy handed it astonished me. I asked a question about some typescript types of an external library, the very author of those types replied and answered my question and I replied that I was happy with his answer and to thank him for his work on the library. The mods deleted my reply. Was it so important for the quality of the site to delete a reply thanking someone for their OSS contribution? Is SO a better site now? Meanwhile they have 10 year old answers still up, with no way to indicate they are outdated unless the author themselves goes through the trouble of updating their answer.
