I asked myself this when looking at the following question. I would like to focus on the writing style, not the fact that this is a "shopping recomendation" question and hence not appropriate:
As can be seen, the original version was/is poorly written; All caps, starts with "I WANT", no structure through spacing/paragraphs.
Let us for a second assume that it is not in violation of the rules, and is a sensible question - it is just written (very) poorly.
A kind soul wants to fix this, rewriting the question without caps, and adding some spacing to make it readable. I was unsure if I should accept this edit, or more general, edits of this kind. If the question is re-written by someone else, people might start putting effort into writing good responses. Thus, the original poster gets answers to their question, but did not put any effort into the question in the first place, perhaps not realizing how vital this is.
How should I/we deal with this? Are there any guidelines?
