So I think most people understand that there are certain tags that are frequently (and in some cases almost always) misused. Perhaps the biggest, arguably, is mvc.
Now, I've read Jeff's treatise on how users never read anything, and I've seen how people continue to post follow-up information as answers, despite having to click through several warnings that they shouldn't be doing that. But, I have to think such roadblocks do work to some level at reducing the behavior we don't want, while incurring minimal wrath from users over legitimate uses.
So this has lead me to wonder about the best way to deal with the problem of frequent misuse of tags.
One option is to "suggest" that the tag may be frequently misused. For instance, when entering mvc there can be an inline popup (non-modal) that says
This tag is almost always the wrong tag to use. Here are some better options. Only use this tag if you really mean "blah"
followed by a list of tags that are most commonly used, similar to how there's a popup when you hover over tags.
This could be an enhancement to the tag management system that allows the tag manager to mark a tag "frequently misused", and then offer some fields for text to fill in the blanks for the better options and text for the "if you really mean" part.
Obviously, this should probably not be used on frequently misused but also frequently correctly used tags, since that could be highly annoying.
As a way to combat that problem, you might look for other tags that are used in conjunction with commonly used tags, such as c# mvc or asp.net mvc. You could also have a little link on the popup that says "don't show me this anymore for this tag" for people that do use the tag correctly a lot.
The impetus for this is that there is a metric boatload of editor hours being spent retagging these frequent misused tags. If this feature could be cut this retagging effort even in half, I think it would more than make up for the effort to implement such a feature.
