Both of you have better English than some primary speakers I know. If it helps though, one thing I do is to read my own writing after finishing a post and ask myself if I'm satisfied with what I've got. If the answer is no then I edit until the answer becomes yes. Most of the time, these edits are just small things that no one else but myself will notice, but that's okay because I feel like it helps me improve as a writer so I can do better by the next post. I assume that's just what everyone does though, so ignore me if you do this already.
