Hm... The titles seem awful, but at least the "Is hiring a “chief intern” a good idea?" one has a very specific set of parameters. It can be answerable with specific answers, and sufficiently answered by a very small set of answers. That said, the answers so far are...
The "Is there a viable alternative to the agile philosophy?" one is from Nov 2010, a more relaxed era, when the site's scope wasn't as well defined as it is today. It was bumped on the front page by a minor edit (argh). I'm on the fence on this one, and I'd prefer it be closed by five regular users.
Edit: Another one, +28 votes, front page: "Is there a viable alternative to the agile philosophy?". I'm not making this up.
