Yeah, the adoption is pretty good, definitely compared to Jython / JRuby. Multiple conferences dedicated primarily to groovy / grails (gr8conf US coming up on Minneapolis on 30-31).
I think Grails is driving a lot of adoption, but I also see it popping up in vendor products that need a scripting language or DSL that integrates with Java easily. Neo4J and Cloudify (Gigaspaces product) come to mind as recent examples.
