See, I’m of a different school of thought: I like reading all the comments added on. Reading the tag comments defeats the purpose of the tag to me, since tagging something is supposed to make it easier to search and highlight. Making tag comments is like spray painting graffitti over a map that you want to use to help you navigate, except now you can’t see where you’re going because you just put spraypaint all over it.
To each their own, though. Cheers!
