Thanks for bringing this up, I hope it gets through to the developers. Oh, another feature request, a feedback section would be nice.

The tag section should be improved asap imho. At least via your first post, one shouldn't be able to create new tags.

In discourse (the great forum platform by the stackoverflow devs) people have trust levels. The more one participates in the platform, the more trust one gains and the more options are unlocked (like creating tags) . This trust is calculated through formulas and automatically granted, so implementing it does not harm the decentralized idea.

I think this would be a great option to clean the tags at least a little bit, and might also help for other use-cases
