It's not nec. the length but the way it is written that I find difficult to get through.  Something this long needs good composition & formatting.  Or to be broken down in parts.  I'm thinking that if I, who will normally read anything on such topics, can't bring myself to diving this diary, well...  You know, writing isn't simply a matter of providing information.  In the end, you have to make people want to read what you write.  You have to tell them right up front why they should care.  You are competing with an almost infinite number of stories on-line!  

Also, I don't know if I am alone in this, but I have difficulty reading very long texts on the computer.  It is unpleasant.  I have to print something like this out if I actually intend to read it.
