Wow, I knew Rosetta Stone was on top of their shit but I had no idea about that.
I've been wanting to learn Korean, too bad I don't want to spend hundreds of dollars on software to do so.
Eh, Rosetta Stone is mediocre for learning a language otherwise. As far as software goes, it's good but software only takes you so far. Rosetta stone does a poor job in explaining grammar rules and actually immersing you in the language. One could easily speed through a lesson and not really remember what they just did. You can't emulate the experience of being surrounded by a language in a 15 minute language. People say living in a foreign country is the best way to learn the language because it's true; you're forced to speak it and forced to try and understand it. It makes you mind wrap itself around the language in a way that can't be done otherwise.
Overall I'd say it's only good if you truly have no option. I understand your woes in particular because while Korean is my first language, living in America for the majority of my life has reduced my ability to speak to conversational. It's very hard to find a proper channel to which learn Korean. Rosetta stone doesn't help me because I want to learn the grammar rules, the structure and expand my vocabulary in an academic sense. My girlfriend however is learning through Rosetta Stone (including live chats) but also regularly searches for online pen pals in Korea or random Korean people to talk to online as well as going to other resources. She's been trying for almost a year and while she hasn't even learned what she'd learn in one level of academic Korean, she's gotten pretty far through some self-determination.
Learning a language is a grand pursuit but know what you're getting into before you try. Endschuldigen Sie, Ich muss schlafen jetzt.
