It seems like a few of my questions have had their titles edited, either to add in capitalization, or to take it out (I've not yet seen both on the same question, though ;). I'm not sure if my title should be "Is There a Style Guide for Questions?" or "Is there a style guide for questions?", though I am now tending towards the latter (see above). (to get the wise-guy badge, you should edit the title of this question.)
Is there a general style guide for questions? Or are there side-by-side good Q/bad Q examples, either here or on meta? Things like: how to make your question specific, suggested limits on paragraph size, etc, etc.
