Do you want to use perlmonks.org as an good example? I mean this in the most respectfull way possible but perlmonks.org is a BAD example.

I remember when i first visited the site (and made my first post) i had no idea where it went, how to look for it, how to navigate the site.

perlmonks.org is the best perl site in the world, but the navigation is terrible. The fact that you have to ask for a diagram sais it all :)
