Don’t forget the amazing site MacCreate and its massive Aperture community. I’m contributing there as well, and deliberately not duplicating tips on MacCreate and ApertureExpert. There’s a LOT of activity on the Aperture site right now over there, as it has multiple contributors and some very dedicated people.
I’ll reiterate what I said in the FAQ here… yes I do contribute to both sites, but I’m the only one running this one. ApertureExpert.com is a small community and will never be as big as MacCreate; I have no interest in competing with my friends over there nor in making sites for all the other Mac apps. There’s plenty of room in the world of Aperture support for multiple sites, so by all means, support them too. They even have a paid membership for extra content.
