Meta Stack Exchange is where users like you discuss bugs, features, and support issues that affect the software powering all 158 Stack Exchange communities.

What is meta?
Here's how it works:
  1. Any Stack Exchange user can ask a question
  2. The community provides support, votes on ideas, and reports bugs
  3. Your voice helps shape the way Stack Exchange operates

Now that tags have this erm... shiny thing which appears when you move your mouse over them (try it! ), one question remains: What in the billion blue blazes does the 'subscribe' button do?

It's not RSS, since a traditional RSS feed link appears beside it, and clicking on it seems to increment the number of subscriber by one, but other than that scouring over the Stack Overflow UI does not appear to reveal anything. Surely this feature would have more use than serving as a popularity contest for the tags?

Apparently it allows you to quickly set up email notifications for a given tag.

Also, it gives a reason to give premium visibility to tag wikis, which is great.

I don't think the subscriber count should be given that much importance; a question count would have more appropriate. Alas, that's a matter for another .

I noticed that too when I rested my mouse on the subscribe button for the [waffles] tag. Hmm... I think I'll unsubscribe now – Yi Jiang Jan 8 '11 at 9:03
