It's a great idea that will probably damage the community. I do something like this privately, or did until earlier this year, when I stopped because it (a) was making it hard for me to read people's comments rather than surveil threads for specific tags and (b) really drove me to invest time in tagging people, which is unproductive since I know so little about the people commenting here and really have no business bucketing them.
