You are a user asking a question, and the system is helpful, so it shows you this:
(the 5 of them were suggested when I finished writing this post, I used only one, tag-wiki-excerpt)
Seeing the problem yet? No? Well, lets explain: there's a common hearsay in meta about tagging and the misuse of a tag, and how people try to alleviate the situation by writing a tag excerpt that explains how the tag should (not) be used, which questions must use the tag and so on, to which most people respond "people don't read tag wiki/excerpts".
And they are right, and is our fault that they don't, I mean, we make them select some tags via "tag suggestions" where it only the name of the tag is visible. The tag excerpt is ignored. They just click and the tag is added without any other interaction.
So, how do we fix the situation? Well, I propose that instead of the tag names, we also pull the tag excerpt and show something like this:
That way at very least (we hope) they will read the tag excerpt, and be able to evaluate if the tag is related to their question.
