This question asks, how do you flip a boolean in C++? The answer, of course, is to use the single-character built-in operator made for doing exactly that.

Now, that's a perfectly good answer to a neophyte's question, but I'm willing to bet that at least 99.44% of C/C++ programmers are familiar with the ! operator, so why did this answer receive 78 upvotes and a bounty of +500?

Seriously, I'm not here to complain about the bike shed problem. I'm really curious whether I'm missing some kind of "inside" joke. Enlighten me, please!

    There was some crazy voting going on in the first year of SO, no doubt. This one however looks like an experiment with the new bounty system, introduced just a month earlier. It worked, well over 4000 views for a ho-hum question. From users who weren't shy about voting back then. – Uphill Luge Mar 1 '11 at 13:27

What bounty, I see no bounty, just a user that was experimenting with sock puppets early in his career.

This is the bike shed effect, in action, mixed in with some deliberate gaming.

  • There is still +500 besides the answer, for 99.999% of the users it means "this answer won a bounty", even if there's really no bounty behind the scenes. :/ – Shadow The Princess Wizard Jan 2 '14 at 9:29
