I hope you do know that for millions of years humans did not consume anything with a lot of carbs in it? No grains, no potatoes and no HFCS and the fruits were quite subpart to what we know now. I've been reading on all of this for 2 years and I think that the dietitians are full of it. A specie does not evolve eating tons of meat with all the fat that come with it to replace that no problem with carbs. So no, eating low carbs diet is no recent fad, it's 3 millions of year life style and evolution. Ten thousands years of gradual ramping up of agriculture will not change that. It's simple logic, no need of a dietitian for that.

Because we're in the middle of 300 millions people speaking English. It's not only a language, it's a culture. And I can assure you that we have not many points in common with the rest of the north america.

It's true that 2 years ago you had to declare your model with xml, but yaml files are now used, a parser does the work to translate them into xml for you. Yaml files are very human readable and you can write your entire model in a blast, as long as it is already planned.

And being a Symfony user since the very beginning, I can tell you that Symfony is indeed very powerful. And that Yahoo bookmarks was developped using it, it says a lot.
