Re: Everybody's doing it ...
All the information on Wikipedia, like all the information on El Reg, is freely available to the public. So you have to ask very carefully what is gained by encrypting the payload. It's well established that traffic analysis works quite well on HTTPS headers. if you doubt that, see https://arxiv.org/pdf/1403.0297. A user under a repressive regime can't conceal very much of what they're doing at all by preferring HTTPS. For a quite passionate debate on this, look at the thread starting at http://www.ietf.org/mail-archive/web/ietf/current/msg93261.html
