Why do I keep seeing a bunch of questions popping up on the Home Page, then being voluntarily removed by their authors? I'm sure I've seen it at least twice now, where I've been on a new question, writing an answer, and BOOM! Suddenly, it's deleted! It's not even one of those junk questions that I'd expect to be closed or anything! And I never see it again... Does anyone know why this happens? (I think it was different users, but I might be mistaken...)
Is this intentional? Is it a bug? Is there a reason why a user would do this that I didn't think of?
Note: I'm not upset, I'm just curious. It just seems weird to me that that would occur, and also if it is a bug, then I guess Meta can thank me later :)
