When I hover over a tag with a mouse, I get a quick count of the number of tag subscribers.
This information is not displayed on either the landing page for a tag or the "learn more..." page for a tag. (I couldn't find this anywhere accessible from the iPad - but perhaps I'm just not aware of where to find this count using a touch device that lacks a mouse)
Can the subscriber count (or lack of subscribers) be added to top right of the tag page .../questions/tagged/tag_name ?
Can this count also be added on the .../tags/tag_name/info page? Adding this to the top or embedding it in the "stats" section on the right margin might be a nice place for the current subscriber count.
