Q:

Do we want an xkcd tag?

xkcd is referred to often on PPCG, with at least 47 questions which are based on concepts or directly related to the xkcd webcomic.
Therefore, is it worthwhile introducing an xkcd tag to group all of these challenges together?

A:

No
Tags are meant to classify questions according to some distinctive quality that they share. Simply referencing an xkcd comic is not a distinctive quality that would create a meaningful classification.
