I'm learning German. I've never learnt a non-machine language before and having just moved to Berlin I thought I'd try not being that jerk foreigner that only speaks english, even after living here for 2 years. So far it's been quite fun. Last week I finally cracked the level where I understood a conversation of a Couple passing me on the street.
An old bilingual hacker mate once commented to me, on learning German, that it's a stack based languages, as all the verbs are at the end of the sentence...
So far no. I've been using Duo Lingo, which has been surprisingly good to get the basics, plus a bunch of learn German audio files I found. I'll probably sign up for classes soon when I find some good ones. A friend of mine took classes aimed at tourists and said she didn't get much from it.
