For one of the forums I’m administering, it would also be useful for tags to have tag descriptions (which, in my mind would be available as a tool tip on mouser-over on desktop) because we have a tag for each command that the program takes via the CLI, such as set. Since it is not immediately obvious why a post would be tagged #set, it would be nice if people could find out.
Having said that my preference would be a fully fledged description field for each tag, here is an idea that might work at least in our case: all CLI commands are in the same tag group called “CLI commands” or so. If each tag group had an option
[ ] prepend tags from this group with _______
So if I’d enter “command” as a prepend string, the #set tag would be displayed as “command:set”
Ah, well, no. It’s probably a lot better with a simple description field.
Just for completeness: another good use case for tag descriptions that can include links is as a place to point out to anonymous visitors that they can subscribe to the tag by RSS (in case they don’t want to sign up just yet …).
Technically RSS for tags works just fine (example), but without a place to point out that feature, users will hardly find it. Except for those with an RSS browser extension.
我也很希望能看到标签描述。将标签下方的描述（如 /tags 页面所示）与标签页上的描述（正如 Dave 上面所发）结合起来就完美了。我们使用了一些生僻标签，对现有用户来说很合理，但新用户却难以理解。如果我把标签名写得足够长以便理解，那在界面中会显得杂乱无章；但如果保持现状，又会导致用户浪费时间来询问这些标签的用途。
