As Flux points out, if you visit the directory of applications at Go2Web20.net, you'll immediately see that "Web 2.0 is really here." This treasure trove of experimentation for the Internet technologist has at least a couple of hundred web services listed. I was immediately drawn to formatpixel:

Create your own online magazines, fanzines, brochures, catalogues, portfolios and more. Using the formatpixel online editor you too can design page based projects, layout text, upload your own images, add interactivity and customise their appearance.

Can't wait to experiment with formatpixel and many of the other apps.
