I don't actually use processing, but admire how the environment and community keep on trucking. The changes for the latest release, 0098 indicates more robustness, and even a save to application function. Previously processing projects were delivered as applets, which can often be a less than compelling experience. Just try getting a browser to reload a jar file if you need to publish fixes!!
Anyhoo, I think processing can be declared a positive case study on how a domain specific language, with a solid dose of evangelism, can make computing attractive to folks not normally inclined to it. Good enough to get you on the cover of Nature and in the Whitney is good enough for me.
