YC started by funding 20 year-olds with no experience, and telling them they were the best people to be doing startups.

We know that our field already has a lot of age discrimination.

Why reinforce that message with grassroots chatter that impressionable new startup founders and young engineers will see on HN?

AFAIK, representatives of other discriminated-against groups aren't coming to HN to voice silly negative stereotypes directly related to workplace performance.

Anyone who can’t see the value in hiring someone with some wisdom is really damn stupid imo. Easily worth it even under a cynical, money-focused outlook.
