I say remove the front page and have a language and an author selected by default and have it as your front page. Beside that, amazing work! Bookmarked and definitely going to use it a lot. Thanks for the work :)
Looking forward for your course on Coursera! By the way, while looking at your introduction slide on http://startup.stanford.edu I've noticed that "Frontend JS Framework" and "Frontend CSS Framework" are in the wrong order (Page 11, Column name "Type").
