For earlier discussion on this sort of thing:
https://meta.stackexchange.com/questions/68647/setting-up-a-faq-for-the-c-tag: this is from late 2010; back then, it seems to have been approved of. But back then there were various questions which were considered on-topic but are now locked as now unsuitable and kept for historic reasons only. Similarly, various meta-tags were approved of then but are not approved of any more.
Special handling for FAQ questions: this one is from February this year but is headed in the opposite direction. Shog9's answer there seems to me to be the best, suggesting basically that having FAQ tags isn't necessary or a good idea. The site's own FAQs are quite close to the contents of the FAQ tag and are most frequently asked ones. (I paraphrase; this is not precisely what he says and is my interpretation of his words.)
Well then, the
[*-faq-*] tags currently in existence are:
- c-faq (done)
c++-faq-lite(sorry, this is an actual genuine tag; it should have had a tag wiki to tell me!)
- perl-faq (done)
- racket-faq (done)
These are meta tags. And as we all know, meta tags are evil. So, should we burninate them?
