It looks like you're going to https://rationality.org rather than http://rationality.org. CFAR doesn't have a SSL certificate (but maybe should get one through Let's Encrypt).
You're right, but now I wonder how it happened (going to HTTPS). I would guess that I googled the address somehow or followed someone's link, but I don't remember anymore.
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
Notes for future OT posters:
1. Please add the 'open_thread' tag.
2. Check if there is an active Open Thread before posting a new one. (Immediately before; refresh the list-of-threads page before posting.)
3. Open Threads should be posted in Discussion, and not Main.
4. Open Threads should start on Monday, and end on Sunday.
