I don't know about facebook, but YC companies seem to be all about building something ambitious but failure prone for a small amount of capital. This is probably easier to do with some college grads who have low living expenses and little established career and therefor a big risk appetite.
Greatly agree with both of you. Maybe "older" founders do better in a B2B world in which they have some domain knowledge, contacts and expierence. Just my guess. What itches me is actually the whole ERP, MRP stuff. So in terms of companies I think I would rather be after the next SAP I think.
