Sysadmin Casts

this looks like a great resource for those with interest in the space

Pretty good idea, and definitely useful! Not a massive fan of the sketch-style artwork but that's just a minor critique.

Nice work. Can others make their own to add to it? Can it be used internally for training videos?

Its a useful resource. Will definitely start looking at it. For sometime i wanted to look at Docker and was happy to find it on this site.
