Ah, I misunderstood.

I was thinking the purpose was to gather tags to drop on posts. Like, for people to discover you.

We could use a small subset of recomended tags. #asknostr and #grownostr are the best I've used.

asknostr to ask for tags to follow relavant to interests, and grownostr to find tags on posts I like.

Of course, there are community solutions aside from tags, like channels, but I haven't found as much activity there.
