The whole tag indexing thing needs to be renovated in general, especially if the current version has bugs. The best solution is an ever-growing index page that adds all tags - even if they're only used once. The view would default to alphabetical order, then can be filtered other ways, no different than when viewing a file browser. Alphabetical, most popular, most recently used, date created, etc.
I also want to be able to mute tags, this way I can continue following the users I want to follow, but can mute the posts they make for tags I don't care to see.
So, say there's an artist on here whose work I absolutely adore, but who posts a lot of political stuff. I don't want to fully ignore that person just because I might think they're overly-political because I love their art. To be able to mute the "politics" tag (which I would love to do) means I could have that cake AND eat it too.
