I haven't written anything in a while and yeah, I know I suck. In lieu of actual original content I'm going to redirect you to two sources. The first is Ambulance Driver who said it better than I could and the second is Mr. Fixit who said it better than AD said he could.
Go, read. I am not a hero, I'm just some schlub doing my job and no I'm not just being modest, I'm telling you how it is.
