I recently edited a post which got down-voted for being hard to understand. How did this edit change too much in the original post? I feel my edit made the post significantly clearer while removing unnecessary text.
I get the feeling that the people who rejected the edit didn't really take the time to go to the question, understand it, then review my suggested edit.
I also understand that there are so many people on Stack Overflow who know quite a lot about the subject but cannot speak English fluently. Hence, their answers become hard to understand. Is it not appropriate to edit the answer to reflect better grammar and to more succinctly answer the question?
