I'm using Safari on a Mac, so ctrl-F5 isn't a meaningful keystroke. Trying a different browser that I've never accessed these pages before with gave the same behaviour. That browser (Firefox) has ctrl-shift-R for a forced reload, and that made the wiki pages for the article itself show your version. However, the history and discussion pages weren't up to date, until I did more forced reloads.
Now even more weirdness is happening. In Firefox, if I force-reload https://wiki.lesswrong.com/wiki/Intentional_Insights, I get the latest version. If I do an ordinary reload, I get Gleb's old version. Force reload -- new. Ordinary reload -- old. I have never seen this behaviour before. Clearly something is wrong somewhere, but what?
Back in Safari, I cleared all history and cookies. Same behaviour as before: one URL gets Gleb's old version, one gets your version. This happens whether I'm logged in or out.
I see that the history has a few minor edits by Gleb around 06:38, 1 December 2015. UDT right now is 22:53, 30 November 2015. What timezone does the wiki run on?
looks like this happened:
by taking the old ININ page and renaming it "delete" it took the history over there to a page named "delete".
Assuming gleb made a new inin page; that would be a second set of history. and be making a mess of the wiki in general.
Nothing fancy; probably not purposefully done to hide the edit history; rather probably done to add permanence to the action of trying to delete the page (and had the effect of messing with the edit history as well)
If it's worth saying, but not worth its own post (even in Discussion), then it goes here.
