When you're on the main page, your favorite tags (on the right column) won't show their excerpt or subscribing link, while the tags appearing under the questions will. This is not narrowed to the gaming site: every stackexchange sites have the same behavior.
Is there a reason to that ? Is it just a way to "keep it simple stupid" and avoid overloading the user interface ?
The reason I'm asking that is that I would find it convenient to manage my favorite tags' e-mail and rss subscribing directly from the home page (since they are listed there).
