Which of those wasn't possible in 1995 with a modern Internet connection? I posit that everything you describe would have been entirely possible with a little less polished appearance 15-20 years ago and that there could be real strong value in starting over and keeping things simple.
Duolingo - because it's not just me learning Spanish, it's us translating English only websites to Spanish. Perhaps I'm not versed enough in the services available in '94 - I didn't really start to use the internet much until college when I got access to the computer labs. Was there something like it around then? I say this because the most impressive thing to me about duolingo ( and the captcha system designed by its founder before it ) is the efficient way to leverages different individual goals to aggregate really large differences for both individuals. Ie the person wanting to learn a new language for free and the person with an English only website that needs to get it translated into multiple languages.
