But q tags aren't used where a literal " character is wanted

You can say that *you* don't use them that way. You can claim that they *shouldn't* be used that way. I don't believe your claim *as stated*.

If there were a way to enforce *how* Q tags are used at PerlMonks, then your argument would have more validity. But if we could do that then we wouldn't have to filter *any* tags (just prevent them from being misused).

Bold/Italics change emphasis. Quotes can change meaning. Quotes can be used to reverse meaning.

Anyway, the potential benefits from the use of Q tags at PM are minimal. We have enough problems with tags that are allowed but can be misused. I find the cost/benefit of adding Q as another such to be a fairly easy choice, though I don't find either side of the computation that great.

And thanks for the education on Q tags.
