Check out Thinkature (unhappy name), the latest web app making use of Ajax the DOM and all those guys. It’s a collaboration/doodling/mindmapping application that’s free and easy to use. Sure, the big firms have Lotus Sametime or this or that high-end collaboration tool; but for the average Jane-in-practice this could be a very very handy thing. You can put up text boxes, link them with arrows, move them around (arrows staying connected), put up images, draw lines, invite others to log in, chat both with text and voice, and then print the result or leave it on Thinkature until you want to return to it. You can also have multiple workspaces. I think Google or Yahoo will be on this one… and change its name.
