That applies to aol, msn, compuserve etc, not to Facebook which you only ever accessed via http from a browser.

Yeah, those didn't count either. AOL and compuserve were not even available outside the USA in the late nineties. With AOL I'm quite sure nobody considered them to be a part of the web. Their pages didn't have URLs early on but AOL "keywords" instead. Compuserve also weren't using http I believe. It was some kind of commercial WAN that was pitched as a competitor to the internet, no?
