I've been going through all the threads in Alternatives, adding tags (kde, palm, android, debian, deblet, mer, easy debian, etc etc etc) to them. I think this will accomplish what penguinbait wants...

I sorted all of the Alternatives threads by number of posts, descending and I'm working my way down the list.

I can only add 2 tags for threads that aren't mine.

EDIT: I changed my mind; I think penguinbait's idea of making a "searchable" phrase at the beginning of threads is a good idea. So square brackets are not good, because you can't search for them.
