While I agree that minor edits as implemented are a bad idea, there are many questions that simply have bad English, but are still intelligible. Fixing them is usually something that I would call a minor edit, but the downside to not editing them is that there are a lot of posts that have bad grammar.
Is there a way around this problem? Should there be a mechanism for dealing with this, or should we just resign ourselves to all the old content that has bad grammar staying that way?
EDIT: I cannot seem to find a nice post with terrible English right now, so this question will just have to do. It has no capitalization. Is it intelligible? Absolutely. Would it look better with the proper letter capitalized? Yes. (this and this are also an examples, but not as good.)
The point is there are many questions that have truly minor things wrong with them on a grammar or spelling level.
NOTE: For a previous post about edit flooding that might be relevant, see here.
