<Something> Stack Exchange is a question and answer site for <some people>. It's built and run by you as part of the Stack Exchange network of Q&A sites. With your help, we're working together to build a library of detailed answers to every question about <scope>.
The text above is the first paragraph in the
/tour page on almost every site. The above link is in HTTP not HTTPS. See for SU:
I only tested a few sites, and MSE is one of a few sites whose
/tour have all links in HTTPS. I'll update this list when I'm happy to do so.
The tour page is OK on MSE, ell.SE/ell.MSE (they contain HTTPS links)
The tour page on SO/MSO, SU/MSU, SF/MSF, android.SE/android.MSE, security.SE/security.MSE (ironic) contains HTTP links
More interestingly, the tour page on SA (Stack Apps) contains an amalgam of HTTP and HTTPS! That's confusing. See screenshot below.
