The problem with job/salary surveys is that the people who respond tend to skew towards the more satisfied and higher paid range. That's why when I was in undergrad, all the jobs seemed so darn great - the companies sent the happiest, chirpiest employees they could find.<p>On a separate note, does jobbook.org look a bit under developed for a publicized app that "took several months"? Maybe there's magic behind that simple UI.
Aaron seems to be using the wiki/notetaking/lightweight approach to a number of things, throwing things up and seeing what sticks. Not a bad idea per se but I have a feeling that each of these projects will need a bit more handholding and followthrough if they are to succeed. But best of luck to him.
I like the idea. Not just for choosing careers, it's also a good source for startups that have a general idea but aren't sure what particular group of users to focus on first, and what special requirements that group has.
Interesting... some of the goals of this sound similar, and complementary, to Path101 (<a href="http://blog.path101.com" rel="nofollow">http://blog.path101.com</a>).
