Trying to maximize fun in language learning is only for lazy learners. Using free web tools like Skype, podcasts, and YouTube to practice foreign languages is only a fad. Using modern crowd-sourced tutoring services like Lang-8, RhinoSpike, LiveMocha, and LingQ are terrible because only those with a PhD are qualified to identify errors in your speaking or writing.
Sorry folks, but the only way to learn a language is attending expensive classes, taking standardized tests, studying complex grammar rules, and memorizing long lists of out-of-context vocabulary. Real language learners know that the process must be painful, tedious, expensive, and time consuming to be legitimate.
Oh, I almost forgot. April Fools!
