@grey.phoenix I think you got the humor in my post, so I'm confident you felt that was not adverse to experimenting, finding new ways and all (a prototyping environment as vvvv exists for this reason).
And having a general knowledge of docs it's not just for efficiency.
It's about "easily" understanding what others do with their patches (and there's a whole load of stuff you can find from other users), so to widen your perspective on the capability of the tools, so to say.
In other words: while it is totally legit to not have used Zip ever, the fact you "missed" them, to me means that you spent a few time looking inside modules, contributions, helppatches and stuff like this. Which instead is, IMHO, what every new user (everyone here has been a new user at a certain point) should do right after learning the basics of interaction (left|middle|right click, double left|right click, and so on).
The reason why is clear, so no need to go further.
That said I've been thinking about this for a few weeks now: having, for vvvv and VL, the corresponding of the 99 Prolog Problems, which is a collections of problems.
The purpose of this problem collection is to give you the opportunity to practice your skills in logic programming. Your goal should be to find the most elegant solution of the given problems. Efficiency is important, but logical clarity is even more crucial. Some of the (easy) problems can be trivially solved using built-in predicates. However, in these cases, you learn more if you try to find your own solution.
Wouldn't this be extremely helpful for vvvv and VL?
