Your point on tags being a snapshot in time is a big reason I wrote this post. I want my tags to be useful. Ideally, I won’t have a different set of tags created on each post. I hope I get to the point where I have some tag-reuse.

For me tags are a snap shot in time. today the tag makes sense, tomorrow I wish I had tagged it differently. Now I just skip the whole thing.

Each to their own.
