Lottery: This idea came from player Louhi, but s/he didn't bring it forward, so I will because I think it's brilliant. A fun way to tame a mildly out-of-whack economy before it really goes bananas (or whatever) would be to hold a lottery. Big prizes, entry price whatever commodity there's too much of, excess quietly disappears.
AstroGlitchery: How about a Giants' Zodiac, tied to the Glitch calendar? Glitches could be Potians or Tiites or whatever depending on when they first joined the game. When the astronomical entity of the devs' choice (doesn't have to be the sun; this is Glitch!) is in your giant's sign, maybe you get a few bonuses related to that giant. Or maybe donating to the giant whose sign it currently is gets a small boost.
I'm sure we'll get some interesting daily horoGlitchoscopes...
