There seem to be two uses of the tag "mono", one for questions related to audio and one for questions related to the Mono framework.
Wouldn't it be better to create a tag "mono-framework" and retag all questions (it's a dozen or so)?
Yes, mono contains 39 questions, so it should be easy to just retag those about the Mono framework to mono-framework and leave mono for audio.
If these are more than 10 questions, you shold probably consider not editing them all at once to avoid cluttering the front page.
