In all online forums, frequently we come across long posts. Indeed it is understandable that complex ideas and situations need explanations which tend to end up as a long post.
Many who browse forums as well as on maillists, have limited amount of time to read and review posts and emails of interest. This is simply a factual matter since many have daytime jobs and they spend time on Internet after hours. Many tend to ignore long posts due to time constraints.
In the above situation, it would be helpful for message posters to post a one para summary at the beginning followed by long posts.
