Disable "Invite to answer"
Please. I have made a feature request about being able to not be invited to answer questions, but that's months ago and it's still not implemented. That's why I know want to add focus by writing here.
I would be really happy if we can soon disable other people from inviting to answer a question. 9 out of 10 times I have no clue at all about the answer and I unfortunately just get irritated instead.
I think you should work on the feed and explore suggestions rather than letter people "spam" each other to answer a thread.
