I've been a reviewer of the videos that Glen is creating. I can absolutely say, hand on heart that I've never seen a higher quality, or more researched tech video about anything. Every one of these videos is world class.
I've been really enjoying bite-sized videos (~15min each) on specialised, wide range of Web development topics. If you're a Front-end or JavaScript developer I'd strongly recommend checking them out. ✌🏻
