"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.
