If the first couple sentences grab my attention then I might be inclined to open and read it. Long form having full support for formatting/markup then makes reading the rest of it more enjoyable. Extremely lengthy kind-1 notes, which by design of the protocol are devoid of any formatting, are not fun to read.  

 that's true but maybe we (I) have been conditioned to simply read alot, I still use notepad and .txt files.. probably too much.
