Don't get me wrong. Learning TeX is probably a worthwhile experience. I was actually trying to get a deeper understanding of TeX, but – to be honest – it's not that easy to get started and thus I gave up pretty quickly. Mostly because there is not that much you can do with TeX even if you mastered it. It's "only" a typesetting system and not really a general purpose programming language (although it is Turing-complete).
