This is a cool app, because it makes it so much easier to explore Smalltalk code if you're not yet committed to loading a particular library - like many newcomers who aren't sure what they can or should do next. It's also a nice look at how using cloud resources facilitates this kind of thing:
Because the Soek project is implemented in VisualWorks, the first projects were exports of loaded bundles and packages from the Public Store. With the help of the Monticello VW package, it is now possible to add projects from any Monticello repository out there. The process of adding a new library is almost completely automated and uses Cloudfork for storing metadata in Amazon SimpleDB and uploading the site contributions to Amazon S3.
