How do you improve your writing by reading? You will partially improve without even knowing it.

I find this to be true. There's is something about some people's writing that instantly show that they are engaging and serious about their topic. Also the formating makes a huge difference. Good use of white (or black) space. Good headings that allow the reader to 'get the gist' at a glance. An invitation for discussion at the end. These are all things that I enjoy in a post and have somewhat adopted on my own posts.

So yes, reading posts lends to much better posts. @ironshield
