Lift a Web Framework , is receiving more attention, growing a commercial user base and gaining momentum. In the May/June 2009 Edition of the IEEE Internet Computing  journal Steve Vinoski  publishes an article "Scala and Lift - Functional Recipes for the Web"  in his column "The Functional Web".
In describing the article he explains, "Lift is a framework implemented on Scala’s functional features. The Scala language offers functional programming features and asynchronous message-passing concurrency alongside a statically typed model. Lift exploits this model to offer secure, higher-level abstractions to Web developers."
In concluding the article, which he co-authored with Debasish Ghosh , they talk of "the power and utility of both Scala and Lift" and "encourage you to explore the references for more information", a serious recommendation to go try it.
"Lift's excellent 'Comet made easy' philosophy made it an absolute no-brainer as the choice of framework for the Apache ESME project. Additionally, the fact that Lift-based applications run unchanged on the SAP's NetWeaver CE Java application server makes this an intriguing approach for enterprise applications in the SAP world"

For developers, there is now a book "Exploring Lift"  by Derek Chen-Becker, Tyler Weir and Marius Danciu, available from Apress  that gives you all the implementation information you need to create a rich Web application in record time.
It appears developing web sites has never been easier.
