Alright, what's up with this weird article shuffling on HN lately? This was in the top position on the home page. I refresh the page, can't find it anymore, spend a few minutes checking my browser history, and suddenly it's at the bottom of the home page. This happens a lot lately, and it's confusing me. Could we at least get a moderator note when the article is moved or a different color to let users know it has been moved? EDIT: Holy cow, now it's on the 2nd page. What the heck? (And I bet I'm never going to get an explanation either.)
