How much equity do you give to employees?
brk: Equity equation...You should give them a vested share amount equal in proportion to the amount of value you feel they will add to the company.  This is usually a variable range (and it varies), but something along the lines of:
  Every new developer adds .25% of value to the company minimum.  Higher caliber people in the same position will add .35% of value.  So your equity range, per developer, will be .25%-.35% (in this example).
