Hello guys, just for fun I’ve created a GWT + Google AppEngine aggregator application that looks like this: It is based on http://www.planetplanet.org/ but just for the idea.

For RSS/ATOM parsing I use feed4j project but it has a lot of problems like: not parsing pubDate element in RSS 2.0 and updated in Atom 1.0 but it’s easy to be add/fix it yourself.

The loading idea was taken...
