I was searching for a tag earlier to add to my question here:
I wasn't really able to find anything appropriate, the closest that was suggested was software-quality. It seems to me that this stack exchange is very much implementation driven - i.e. it's more closely related to programming / software specifically.
I'd be hesistant to suggest the tag "meta" given it's implication on stackexchange generally, but I'm not sure what else / if anything would be appropriate.
