I really like the idea of the site, and the mission to limit the number of things on it. Too many options, and I just get choice paralysis.

However, to be frank, I don't know who you are, so why should I trust your recommendations? I wouldn't mind if you were the only person to decide what gets posted, but I would like to see content from users, primarily tags, votes, and comments. This might also increase user engagement.

You could also make it "social" if you wanted. Allow users to publicly commit to doing a certain tutorial X hours per day/week, and you track that from when they click through your site to the tutorial site, and then they check back in when they're done. Or it could be complete honor system. I wouldn't worry too much about people lying, because really, they'd just be hurting themselves.
