Anyhow, it's important to note that last year there weren't all that many Groovy related talks either, but what I observed was that Groovy was represented as much by excited attendees as by presenters. I think it can be the same this year. Some of the brightest minds in the G3 community will be at JavaOne and they will have many opportunities outside of the session rooms, to talk about and demonstrate the power, efficiency and fun of Groovy, Grails and Griffon. The rest of us can do the same. So if you can make it to JavaOne go for it and feel the Groovy in the air!
Speaking of enthusiasm in the community, here are a few examples:

This one is from the Stephen Colbourne's blog and shows the results of a whiteboard poll at Devoxx, a European conference that is very similar to JavaOne.
So don't be discouraged- the better mousetrap is doing all right!
