wikiCalc is a mashup of a wiki and a spreadsheet. Dan Bricklin, the inventor of VisiCalc, the first computer spreadsheet, posted about it on his blog when he first released the beta. Now, the application is out of beta and ready for you to put through its paces.
The application works like a wiki as part of a web of potentially editable pages in a collaborative environment. Imagine a streamlined Web-based Excel that’s a living document. Dan’s idea is both simple and powerful. In his own words, wikiCalc is “a complete server-based spreadsheet that runs on your own server, not only on a service provided by others.”
Dan thinks anyone concerned or responsible for any of the various forms of compliance will find the audit trail that wikiCalc keeps quite helpful.
