Interesting, but the point on "Democracy" seems a bit an applause light to me. We all like democracy so a community needs democracy, right ?

Well, if you look at communities, you'll see that "leader worship" is actually as least as efficient to build a strong community than democracy. I'm not saying it's the best option all things considered, but if in the purpose of crafting a community, having a strong, quasi-dictatorial leader that everyone respects tends to be a very efficient way. The "penguin" is a clear example of that : Linus, the "benevolent dictator for life" is a strong factor of the community cohesion. Democratic models can also work (to stay in the same domain, that's how Debian works, and it works very well) but they aren't the most likely path to success.

There probably are evolutionary psychology reasons behind the "strong leader" pattern, rooting into families (were the patriarch or the matriarch is the natural "strong leader") and tribes (which usually aren't very democratic), the two most primitive communities, but I won't enter the details because evopsy isn't my primary field.
