Does anyone have a pointer to a list of these lists? Would be interesting to know what models people use on a day-to-day basis, like usesthis.com for the brain.
Regardless of what you settle on I'd look for the equivalent of http://www.packal.org/workflow/alfred-pinboard for whatever service and platform you use. Being able to instantly search through all fields of all items in your archive is pretty great and has changed the way I work.
