I leave out visual design because lots of startups that meet every goal you can eventually imagine (ginzametrics, bingocardcreator) don't even go close at having a decent visual design (no offence intended).
I believe visuals are also a very subjective matter, and belong much more to the "talent" side of things, than to the "knowledge" one.
