I think you've missed my point.  I have never pretended to know what I am talking about.  But a monkey can read the paper and figure out when things don't add up.

There isn't anything in this dairy that requires outside knowledge of events to understand.  Or is there?  Maybe I can't tell anymore.

I suspect it has nothing to do with specified knowledge and everything to do with specified interest.

In fact, the whole point of writing diaries is to inform people or start a discussion, not to exclude people unfamiliar with a topic.  IMHO.  It's precisely by reading people's diaries that I learn about subjects I have no background in.  And I've never been aware of anyone needing credentials to make comments or ask questions (or write diaries, frankly.)
