Another great quote, this time from Henry Ford:
If two people always agree, one if them is unnecessary.
The quote applies very well to open source development -- what makes open source so strong is that such wildly diverse people, with different backgrounds, ideas, approaches, languages, IDEs, interests, itches, sleeping habits, coffee addictions, etc., come together and work on the same problems.
And lots of disagreement ensues.
As long as the resulting discussions are driven by technical merit and not personal attacks (ie, The Apache Way), and consensus is eventually reached, then the disagreements are very powerful.
