How would subscribing to a tag differ from using its feed? Or creating a single tag subscription?

The problem with the current subscribing system is, that it is limited to 8 groups x 20 tags = 160 tags and there are way many more artists than this. It would be nice to have at least one group, which can contain 200 to 500 tags, just to add artists.

We've been looking at how the sub system might be made a bit more usable...

And as you said, it is really hard to add subscriptions and using the feed-system. The most comfortable way, I can think of, is to add a plus-sign next to the tags in the posts, where you can choose a subscription list to add the tag to.

It would look like this:
