"Advice" isn't a commodity. How much it's worth depends entirely on who it's coming from and whether they back it up with action. YC fight hard for the startups they invest in. For that 6% you're not getting idle advice, you're getting YC on your team. It's a rare early-stage startup indeed whose value this wouldn't increase by more than 6.4%. For most, getting into YC is a state change and has profound effects. Since by the looks of things you've created an anonymous account specifically to question whether YC is worth 6% of a startup, I think at this point you should either back up your assertions with something credible or be dismissed as a drive-by troll.
