1. If you blog about something it's a good as a go to source in future, be it programming problems you have to solve again or arguments on the internet (here's one I prepared earlier). 2.

None of my friends are developers so my old man rants (a skill is still in it's infancy for me) are lost on them. Edit - The spelling mistakes indicate I still have room for improvement.
