One complaint that applies to most other salary apps (and mainstream reported numbers) too: unclear definition of salary - does it include bonuses, RSUs, options, etc. amortized annually? Without that, it seems to me meaningless to consider two 180k salaries as equal when one is making only 60k in bonuses/RSUs and another (let's say more wall st oriented) making 180k in year-end bonuses. Are the salaries I'm seeing on the site base salaries only? If so, how are you guys planning to address the above issue? Otherwise, I do love the idea of the Salary Fairy (and FairPay).
