If you're a founder and you're vesting, you already have failed math and really should go work for someone else. :-)

Seriously, you founded the company and earned the shares... you paid for the investment when you were dilluted by the shares issued to the VC.

Any VC that asks you to re-vest is just double dipping, wants more power, and wants to be able to more easily push you out of the company.

The people behind venturehacks are VCs, they are posting from the perspective of wanting to be able to double dip like other VCs.

(and anyway, its 2007-- you don't need venture capital.)
