These days, if I want to learn something new I tend to start with YouTube, and then read more if I still don't get it. I've changed headlights (don't laugh. These headlights required removing the bumper and grill assemblies), and sweat pipe starting out this way, but also learned about VMware, OpenStack, and Big Data.
To wit, we've spent a lot of time as a team in the studio lately, explaining stuff in a more visual way. The best way to see the collection is to look here. You can learn about ZFS for VMware, cloud, OpenStack, Database, using encryption, etc.
Let us know what you think, and by all means make requests for new topics.
