WikiCalc is a new piece of online software from Dan Bricklin that is attempting to bring the venerable spreadsheet to the Web. NewsForge is running a review of the initial alpha release and it seems pretty good. Recently he was interviewed on the Gillmor Gang about this software and his ideas around it. It is a fairly nice idea now that we live in an Internet full of Ajax and rich interaction. My initial feeling was that he was angling for a Google/Microsoft/Yahoo buyout but surprisingly he has put the source code online for others to download. This is a good thing from a free software perspective and hopefully with the support of others there will soon be a viable (and hopefully embeddable) spreadsheet application for the Web.
Various pieces of writing from undertaking my PhD thesis entitled "Building Digital Bridges - Improving digital collaboration through the principles of Hyperlinked Practice". I undertook this research at Victoria University of Wellington between 2004 and 2010. My primary supervisor for this thesis was Michael Donn.
