Duolingo is good for understanding structure and is far more mobile and immersive than RST. I agree with most of the comments here that it's difficult to find a full-service solution since different learners have different needs. It's very interesting that general consumers recognize RST for what it is: a massive marketing machine that took a standard, linguistic approach to language learning and applied it across many languages. What other products are so bluntly recognized as overpriced but fantastically executed from a marketing & sales approach to where year in and year out people are coming through the door?!?! I would argue that LiveMocha was just as guilty of applying a standard solution across many langauges. Different languages require different methods and approaches. I run http://lingo-live.com/ http://lingo-live.com/ which is focused solely on Spanish. As a result, we have a small customer base who NEED or REALLY WANT to learn Spanish and have catered our product to this very specific need (also we further segmented our users into people who mainly want to SPEAK Spanish vs. write or read it, have very busy schedules, and are comfortable accessing their learning entirely over the internet, including live lessons with their tutor over Skype). Not having to worry about how we teach Chinese/Portugese/English/Esperanto... is a huge benefit and we can rely far less on ad spend and more on referrals and WoM since our students are actively engaged with our Spanish service and have someone keeping them accountable to their learning. Then again, the number one answer we get when speaking to potential students when we ask how they would have gone about searching for a Spanish learning solution is "Rosetta Stone Spanish". Maybe the marketing is more powerful than WoM but how sustainable is it? RST has been running in the red for the last 3 years despite some significant cost-cutting and there are countless articles about the inefficacy of their solution (a few below) http://language101.com/reviews/rosetta-stone/ http://language101.com/reviews/rosetta-stone/ http://www.fluentin3months.com/rosetta-stone-review/ http://www.fluentin3months.com/rosetta-stone-review/ http://seekingalpha.com/article/254261-why-rosetta-stone-s-strategy-to-revitalize-itself-will-fail http://seekingalpha.com/article/254261-why-rosetta-stone-s-s... I don't believe LM offers them much in the way of technology but it will be interesting to see what happens with RST's balance sheet behind them from a marketing perspective. The acquisition was a great deal for RST even if they dissolve LM.
