Maximize salary/cash pay. Early stage startup "equity" is worthless.
If I would maximize that I'd just go to Facebook or something like that. Sticking to startups for now.
Good luck, commander.
In 5-10yrs you'll be giving this advise to new wave of enthusiastic developers bought for lots of "equity" and little cash.
Use your FB salary and fly to Vegas. You'll have better return on investment than from average startup equity performance.
