I've got five books in print and 20 odd peer-reviewed scientific/academic journal articles. Doesn't make me immune from crap writing though. Quite often what you think you've written isn't what you actually have written. When you've got an editor, your mistakes get picked up. They don't get picked up on an online football forum.
Having said that, one of my big things is making my subject interesting and accessible to the general public. I often have to deal with the work of other people who write so badly (even if it is scientifically accurate) that it makes the subject boring even to me. Surely, anything you write, you want people to engage with.
