Hammy -- I think that Tolstoy's observation on happy family's applies here. Happy people are all shiny happy in the same way. Why write about what everyone (at least everyone happy) all ready knows? OTHO sad/depressed/miserable ppl are s/d/m in their own unique way -- hence something original and easily nodable.

Personally I node day logs when I'm depressed so that the people around me don't have to hear my rants. Which brings me to my next point

Our good lord am I bored!!! Not depressed or particularly sad, but pecking out this node is the most exciting thing of done all day. But that's my fault.
