I frequently see RFCs being mentioned by number only, not mentioning what they are about. It's a quick google search to find what they are about, but the post might as well have mentioned the title. For example RFC 2616 is about HTTP/1.1, but who knows? Why should you know?
The title of the RFC is often mentioned in parenthesis behind the number, which is okay, but most of the time there isn't really any reason to mention the specific RFC. When there is, it's obviously fine to mention it, but otherwise who cares?
It's a bit of a pain to have to go and edit every post doing this, but we could at least encourage users to use titles instead of numbers. A link to the RFC is quite the minimum I think. We might actually automate that and parse links out of
