I do not intentionally make my posts that way, that just happens to be how they form as I write them. I could make my posts shorter and specifically my suggestions about things here more succinct by appealing to idealism or by using empty mantras; i.e. development is good, let's do it this way because it worked in the past. Let's be honest though, my posts are either misunderstood or ignored, regardless of their length.
About the screen size though, I do not think that it would be bad if there were a wider option available. Not sure how hard it would be to implement with the forum and the site, but I don't know, if it existed, I might use it.
