Let's nuke the catch-all tags
Surely all questions here are polls, in the sense that people vote for answers they agree with?
If the [poll] tag was useful, wouldn't this question be tagged with it?
I also disagree with its use on SO, along with other meta tags: they describe the poster's intent or motivation rather than the question's content. You could say the poster's intent is the question type (of which "poll", "homework", etc. fit), but those still aren't about the content of the question.
It was a long time coming around to this opinion, though, and it's broken on this very site: [discussion], [feature-request], [bug], etc. These categories are needed on a support site (with [discussion] merely because we mix it with support), while they don't seem to be on a Q&A site.
Is everyone OK with the tag being removed?
Quoting TheLQ's comment on an answer at Adding discipline to programmers.SE:
... If you look at it, all subjective questions are polls, ...
As most questions could be tagged with [poll] and nobody speaks up it really seems like a redundant tag.
I have a strong believe people would agree:
The poll tag is
As of now, it's gone...
Those that disagree should start a serious meta question with a reason for such tags to exist.
After waiting some days, a lot of people have agreed and nobody has disagreed...
