Too big to fail works when there's a network effect that locks your customers into you.

VISA is an example of that. Reputation-based businesses (Think auditing firms) are another. Facebook is a third.

On the other hand, a vendor like Nortell did not have network lockin on their customers. They could, and did end up switching vendors.

"Switching", get it?

My hero! Bro who is going to be the voice of reason in this crazy mixed up world? If I were an archaeologist in the future I'd start by reading all the most downvoted comments for sure!
