Paul, re: your comment "all other things being equal" -- wouldn't you agree that some investors are not at all equal to others? (YC itself included)
seems that GV resources are worth something more than other investors checks by themselves. while i agree there are many investors who are "just a check", there are at least some who bring a lot more to the table than just capital.
anyway, i understand the timing issue of subsequent / lower cap deals, but i wonder if this isn't just a result of a sequencing problem for diff "hi-res" financing negotiations within a period of 30-90 days around the same raise.
