Here at the IAJ, we have been shifting an increasing amount of our computer application work to Web-based tools.  We do this in (a) a spirit of experimentation, but equally important, (b) it allows us to share ideas, work-product and records with colleagues literally around the world.  Hence, it was fun to come across this contest results site that pulls together a couple dozen of most-interesting not-on-your-desktop applications.
And this is just the beginning, we think.
