I was thinking about this earlier today. I tend not to read incredibly lengthy posts unless it is a topic I am interested in and I am interested in what the poster has to say. I would have to say on average if a post is longer than a paragraph (4-5 sentences) I usually skim the rest or stop reading completely. All the one-liners I have a tendency to read. And if the post is of a member I couldnt give a damn about I usually do not even read beyond one sentence. However if its a member that I like or are interested in their opinion I will read pages if they type it (Constantine and Kaz are two that quickly come to mind).
