> Y Combinator transforms this force from a weight on your shoulders that keeps you down, to a powerful rocket that propels you to the sky.
To me it sounds like someone that has just had some kind of epiphany.
If a dutch person would say:
"Y combinator verandert deze kracht van een gewicht op je schouders dat je naar beneden haalt tot een krachtige raket die je de lucht in schiet"
We'd think they might need help. Or at a minimum that they should stop smoking that stuff ;)
For instance the 'zany' in the text above I had to look up, and even after looking up it doesn't make much sense to me.
1) a subordinate clown or acrobat in old comedies who mimics ludicrously the tricks of the principal
2) a slavish follower
3) one who acts the buffoon to amuse others
None of the three are a preferred candidate when I do a simple substitution.
