Well popularity is not really the reason I'm interested in these languages. The practical guy in me tells me to stick with the languages that I know, and expand my knowledge in that domain. But then there's that other side of me that's really interested in everything. These days I'm leaning towards being more practical, but I was always interested in just about everything (be it programming, music, 3D/art, or even various sports).
And you're absolutely right about making decisions, they have to be made. Anyway, I don't want to steal the topic, but thanks for the handy reminder. :)
