Dhanji R. Prasanna was a developer on Google Wave

[A]s a programmer you must have a series of wins, every single day. […] It is what makes you eager for the next feature, and the next after that. And a large team is poison to small wins. The nature of large teams is such that even when you do have wins, they come after long, tiresome and disproportionately many hurdles. And this takes all the wind out of them. Often when I shipped a feature it felt more like relief than euphoria.
