I often think about how much more cost effective some companies' products would be if they would decide their product is "done" and that they accepted moving on into a cash cow type of phase.

There are major websites and web-based products like Craigslist, Wikipedia, and Steam that are handling insane Internet traffic with comparatively tiny levels of staffing when compared to YouTube or other giants.

I think those companies have accepted that there is no rush to make major innovations or changes and that hiring a large army of talent is far less cost effective than having teams that are small enough for everyone to know each other.
