Edit: I finished writing this without answering the question. "MBQ" makes a point I have to agree with. Editing, if done properly, can only help the site. I remember poor questions are improved by editors all the time on Stack Overflow. Additionally, imagine the distraction of correcting and discussing these items in the comments below the question or an answer.
I would like to include (correcting into) proper, understandable English under "wrong wording" as well. I see too, too many questions on SO, Pr, and other sites that are not even phrased as questions, or simply need revision. The question headings are the face of the site, and a low standard reflects poorly on the site as a whole (and looks unprofessional, not that we are "professionals", but we should strive for a high standard on all the sites).
As for the moderator problem: I have suggested having "voting drives" where you can pledge, say, 3 votes per day or 10 per week (to me!), in exchange for special prizes or privileges (to be determined)! I was inspired by politicians and a local radio program. (A classical radio station was encouraging "pledges" in exchange for membership benefits and such). Wikipedia does this, but without direct benefits to the donors.
