What I like most is the personal help. It promises not just a video but guidance to the best video based on where the "noob" is located... that's awesome.
I would say that "passively by dropping comments to the blog" feels like a low bar (but maybe I'm reading too literally?). The response rates to questions must be prompt – the difference between getting an answer in 30 seconds and 10 minutes is huge for me, and I've been writing software for 15 years. It's only worse for beginners.
For our students at Thinkful (http://www.thinkful.com/) getting human contact promptly is key... our students only like banging their heads against the wall for so many minutes before getting demotivated!
