There are a lot of people out there trying to compete to be your front-end Ajax/ web 2.0 framework of choice.

In the midst of technical framework comparisons, ask yourself, "Where is the RIA Industry Going?"

Well, we'll tell you. Prototype and Scriptaculous lost the early mover advantage by not focusing on good documentation.  After all, how good is a framework if the learning curve is too steep?

Extjs came out running, first focusing on documentation and benchmarks, then licensing, training, and, consulting.  A more than cozy relationship to Adobe, and now the addition of GWT support means, [wink wink], looks like someone's positioning to get bought.

We wouldn't be surprised at all if Adobe bought Extjs, given all the integration work Jack's done with their AIR framework  and Adobe's eagerness to get yet another generation of web designers coding javascript without any clue as to what is going on under the covers.

And more power to them! We feel the future of RIA's is the 'Next Plateau' where frameworks are absorbed into IDE's and online content management tools.

And what is Clover Leaf's part?  Why that part is simple.  We are moving our customers and partners forward ahead of the curve.
