There is indeed no such culture, @XanderHenderson. See the meta posted by Martin, especially the
answer. Indeed there are new tags coming up almost everyday, it is not realistic to have every new tags discussed. For some specific subject, it is even meaningless to post on meta since it is too advanced/localized. In particular, it is now Saad who has strong opinion against the tags (e.g. I did not retag the tag back after they edit it away)..
