When you join together the terms “online” and “whiteboard,” you probably conjure an image of some super-simple utility that allows one or more persons to share ideas. Companies like 37signals and Stixy offer such services. Yet they don’t take literally to the concept. Sure, they let users toss up text and files and so forth. But they don’t offer spaces totally open to a myriad of inputs, including free-form drawing and line figures and so forth. Scriblink appears unique in that respect.
