I tend read a long post, if someone goes to the trouble and it is important enough for them to write.
This tends to expose me to run on stuff, but if it is quagmire, I will begin to skip through.
I'm one of the most lengthy writers on the board. I try hard to keep it precise, but then I like to be thorough.
I am in the mood, or have some time, makes the difference to how much I kick back and read. If I'm hurried, or tired, I'm less apt to take as much time in consideration of someones point.
