EDIT: see the Jeff Atwood's comment below. Should we just kill this tag? I think so. Please weigh in.
For the highly-used but poorly specified equipment tag, I proposed the following tag wiki.
Photos can't be taken without equipment, so this is implied for most questions — tagging them with this isn't really useful. Identify the specific type (but not necessarily exact brand/model) of equipment instead.

Questions which deal with artistic or business aspects of photography don't benefit from lacking this tag: they can stand on their own merits.
for the tag wiki, and this was rejected by a moderator. I understand that the dis-recommendation might be a bit controversial without discussion — but I still think this is a pretty weak tag and stand by the suggestion.
What do you think? I'm particularly interested in hearing from people who think that this is a useful tag at all, because maybe there's something I'm not seeing.
