Quoting jayjg jayjg99@gmail.com:
a) disbelief and mockery (the word "rutabaga" comes to mind)
I don't think that the rutabaga example was intended to be mockery but rather a point about what was happening to encyclopedic content in a method with minimal community input. People can use humorous phrases without mocking. Indeed, sometimes when a topic is sufficiently serious, a bit of levity can be very helpful.
