"Surveying OS Ajax Toolkits" article on infoworld

This is well worth a read. Unlike most reviews I've seen, this author obviously spent sometime with each of the libraries he includes - enough to get a meaningful impression of the strengths and weaknesses. For me, he's right on the money with Dojo, YUI, Rico, Atlas. I differ a little on GWT, but in truth it sounds like he spent more time with it than I did. Being a dojo guy at present, I think there's lots in there he missed or didnt mention, but the overviews are fair IMO. Oddly, he didnt review Prototype/Scriptaculous at all.
