Cool idea! Is it mainly a science/tech directory, or do you plan on incorporating other online learning resources (like language learning sites/books/etc.)? It looks like mainly Khan Academy results show up for me. Also, you have "Communication" as an example search term, but it doesn't return any results.
Thanks! No, we'll try to cover all topics. That's just the beginning and resources like Khan Academy are highly respected and useful, that's why included it from the start.
As for the search term, the search algorithm isn't perfect yet, working on it :)
