I like the way Marc Fest thinks.  He not only thinks about similar problems as I do, he also likes simple solutions.  His Quickbrowse.com is a simple idea with simple benefits: replace page-flipping browser tedium with quick scan down a single page.  OnlineHomeBase.com is another simple yet effective idea: server-side PostIt notes.  Thanks to Scott Loftesness for mentioning Marc.  I got a smile out of the deal.
