Looks awesome, but the software side of things is a little bit empty.
Adding one video at the time also feels like like a lot of work so I wonder if it would make sense to add an option to suggest YouTube channels instead of individual videos. Then your site could list the latest and/or most popular videos from that channel...
right now it's just a list of videos I watched on my own time and think was very good quality. The site definitely needs some more automation similar to what you suggested but its still needs to be moderated. I don't want to just link to every video people put on theirs channels.
