List.It, FeedMe, NB, Exhibit

Last October, we had a visit from David Karger, speaking on "Building User Interfaces that Entice People to Manage Better Information"; only now, alas, am I getting around to posting it on my blog. He spoke on four systems: List.It, a note keeping tool that runs in browsers; FeedMe, a tool for sharing interesting things you find on the web, NB, a collaborative tool for teaching environments, and Exhibit, a Javascript library for posting Excel spreadsheets as web pages. (The screenshot above is from Exhibit.) What I particularly liked about his approach was the interplay between design and experiments to determine how users interact with the systems.
