I would like to learn it because it's "the language of the smart", and because that would make a very interesting hobby. I already know some words from Duolingo, but I still need to expand the vocabulary and get some grammar. One of my biggest problems is the way that I manage my time.
Wheelock's textbook was the standard for learning Latin back when I studied it over a decade ago. I personally wouldn't trust generic language learning apps like Duolingo and Rosetta Stone for a dead language, especially considering how poorly they do in some low resource yet still alive languages.
