I stumbled across this recent meta question on the computational science site. What struck me was one of the community associates pretty much declaring that the homework tag should be abolished, since it is a "meta" tag that deals with the style of the question itself, not its objective content. He links this blog post about getting rid of such tags, but that post was very specifically about subjective, best-practices, and beginner on the original SO sites, with no mention of homework.
So, do we like having the homework tag to set apart questions for pedagogical reasons? (Note this is independent of whether we like the quality of such questions; this is framed in the immutable context of such questions being allowed.) Also, is there a chance all our homework tags will one day be purged for their... impurity... or something like that?
