For me I'd rather have a good speaker talk and walk through the subject matter than read about. As I can process audio faster than text.

The other side to this is that blog posts are full of people that don't write well or who are optimizing for search engines. An extreme version of this is cooking recipe posts, but I've seen tech articles that are moving this direction.

I also occasionally watch some live programming videos casually when I'm not focusing on anything and I've learned some things that way. For example, if they do something differently than I would have it's cool to see how it works and why they choose to do it that way.
