My 2c on Rosetta Stone
There are plenty of cost effective alternatives to Rosetta Stone, I’ve honestly never looked into it because the cost is prohibitive. If you’re hungry for learning then as your skills develop you’ll want to attempt a variety of methods. If you switch and change like you need to every few months then you don’t want to be paying hand over fist for every new method.
I wasn’t surprised to hear Gary’s comment that Rosetta Stone is an adaptation of US State Department Language Lessons. You’re in to remix culture right? Role your own!
There are so many ways to get authentic content, and replicate effective methods at next to no cost. Where all of this self paced study begins to shine is in your friendships with people who speak Japanese. Without making these friendships, you’re missing out on the cultural component, not to mention subtle nuances and regional differences.
The LinguaLinks Article - A Few Simple Ideas for New Language Learners http://bit.ly/l1xS3 is essential reading for self directed learners. Some of the articles here go into detail about discovering your learning style and finding the best language resource partner (your exchange partner). It’s a bit dated now and probably needs someone to give it the Web2.0 once over, any takers?
