The http tag has no tag wiki/excerpt and 19 questions about various topics. Since Stack Exchange doesn't work over HTTP anymore for quite a while now, isn't it time to burninate this tag? I see some questions which should receive the https/ssl tag, for others architecture might be more appropriate.
Links can still be HTTP I suppose, but then again, HTTPS would work just as well for those I presume, if it is about insecure / secure.
More importantly, anything to do with HTTP - the protocol - might still warrant the tag. If there are any bugs in that then I'd expect http. HTTPS is nothing more than HTTP over TLS after all. There are quite a few questions about that (HTTP headers, HTTP error codes) etc. Tagging bugs in the HTTP protocol as architecture doesn't make much sense to me; that's about implementation, not architecture.
Of course, I'd imagine that the low number of questions is a problem, and if we go this way then the tag should get a description.
