I try to write in this style for longer posts. People have commented on this in the past but I never figured it to be a big thing.

It seems to be hard for most people to write in spoken language. So perhaps the best solution is to write your first draft the way you usually would, then afterward look at each sentence and ask “Is this the way I’d say this if I were talking to a friend?” If it isn’t, imagine what you would say, and use that instead. After a while this filter will start to operate as you write. When you write something you wouldn’t say, you’ll hear the clank as it hits the page.
