I use ExtJS for an application that I created. While I find it's licensing model an annoyance I have also found that, for the facilities it provides, it's unmatched in terms of quality and breadth of offering. I know there are a number of other potential alternatives out there but I have found that I like the way the components look, it's strong in the cross browser support arena and believe theres a coherence to the API that simplifies learning how to use it too.

My concern is that it does not really foster a community around it so with the odd licensing model and without the community itself it can slow behind other alternatives.

I can't argue with that but I suppose the way that they are looking at this is that, as it's least partially a commercial venture, there are people being paid to keep it concurrent. Only time will tell whether this is how it actual works out however.
