The cynic in me wonders which 20% we'll get. The repo linked here is pretty impressive, so I may have to eat crow. I would have expected to get every html template and vba macro ever written, instead of the value add stuff.
My thoughts exactly. That 20% will probably provide you with a map of Russia while you're flying over the Swiss Alps. Some things are better not learned (or known) at all than learned (or known) the wrong way.
