in reply to (OT) "Learn one new language every year"? Yeah, right.
But I don't buy the advice: "Learn at least one new language every year".
How about "Learn at least one new framework every year."
Things have calmed down in the language space, and the energy has moved into frameworks. Already learned Python? Study Zope. You can easily spend a year there if you're limited to a few hours a week. Learned Ruby? Experiment with the Rails framework. Plenty of good ideas there.
