> they built their software so that it could grow to 2 servers

This is somewhat debatable -- all software can be grown to multiple nodes, it's more a question of how much work is involved.

They built their software to meet needs. Then, later on, they worried about the other stuff. That's a good way to determine whether the other stuff is worth worrying about.

See also the WebVan analogy for an example of the converse.
