Ok, I'll come out and ask the dumb question: WTF is 'q/dau'?

21. hacking.
previously @spire, intern Nethermind, epns.io

Is this a crypto-ism or FC-ism? 

Years and years in marketing and growth, and never head it before.

FC, think dan coined it
basic idea is that you don't count bots, spammy users and so on

idk how they calculate it internally though, maybe something similar to active badge so ratio of engagement to casts

well, its a term used around here, probably started by dwr.

but i guess applies everywhere, even more so for crypto i think. 

very likely that q/dau growth over the last week is a fraction of dau growth.
