In Please don't migrate low-quality questions to other sites , there's reference to "Some random guy who thinks that maybe he can get an answer, whether it's badly worded or not."
I often find badly worded questions a sign that the person asking it hasn't put a lot of effort into the question, and probably hasn't googled his question or even thought about it before asking. Likewise, we joke about "plz send teh codez", suggesting a link between question quality and English grammar.
However, is this a reliable indicator, or does it only apply some of the time?
