The best tech. for me is still Anki.  It allows me to add new words pretty much anywhere I hear them and study when I&#x27;m on the go.  It also is smart enough to know which words I know and need to work on.<p>All of these new sites popping up are really just gimmicks.  Studying a language is damn hard and needs complete dedication to get anywhere past the basics.<p>I&#x27;m on my second foreign language and I have joined a few meetup groups to meet other people that are also interested.  Most people give up after awhile.  I think I know only 1 or 2 people that have continued to study a foreign language as long as I have (6+ years).<p>Until we have universal translators, nothing will replace hard work and dedication.  These sites are catering to the people that want an easy way to learn a foreign language.  Some short-cut that gets around all of the boring, rote, memorization.<p>What I have found is that the same type of effort it requires to learn a foreign language is the same that is required to start a business and make it successful.
