My usage of “X” has changed. In the beginning I found it to be a valuable networking tool that added value to my business. In retirement, I now use it as a news aggregator- so,etching it does quite well for the topics I am interested in. The discussion element has long since ceased to have any value - for the reasons given above.
Threads has yet to establish itself but is a (for now) much nicer place than “X”.
Instagram is a useful means of keeping tabs on nephews and nieces who post pictures on there from time to time. The algorithm that shows you suggested posts is a pain in the proverbial.
