I'm just a bit worried that we're all missing a trick here by focussing on how collecting is made simplier for US by using SAE.
Despite it being a pain, I've picked up loads of work by having those face-to-face 2 minute conversations at the door step, such as I was going to ask you to clean my guttering, my friend wants a window cleaner and two doors down have moved and even so-and-so says she's not seen her window cleaner for a few months.
Surely, thats what building a round is all about ?
