LOTY. Learn a new language each year. This has been a persistent theme for several years... I first heard of this reading The Pragmatic Programmer a decade ago. It's golden advice if you take it... I haven't as much as I should have!
Today you have an opportunity to put the advice to use and learn one of the new JVM languages. Venkat Subramaniam's new Scala book just went into beta! (link). This means you can read it now, and offer feedback on the parts you don't understand or have trouble wrapping your head around. And Venkat can fix the book before it goes to press.
In other words, you can get Venkat to write the book you want to read. ;) It's not quite that cut and dried, but it's a great start. If you're considering Scala as your next Language of the Year, this would be a great way to begin.
