Why Groovy? * Groovy is easy to develop in - it's dynamically typed and far less verbose than Java * It's mature and stable * It's easy for Java programmers to learn * It's easy for Python and Ruby developers to learn * Grails, groovy.sql.Sql, XmlSlurper and a host of other Groovy libraries * Documentation is good and support forums are very active * Groovy is actively developed. Version 1.8 was just released. I haven't had the time to look at the new features but glancing at the changelog they look pretty good. * And last but not least, Java shops with a heavy investment in Java and Java servers can easily integrate Groovy as opposed to rewrite things in Python and Ruby (For green field development I still prefer Ruby)
