I've been a huge fan of Talentopoly for a couple years now. Even as a low-level still-learning developer, it's been invaluable. The Job Boards idea in a more 'intimate' setting seems pretty brilliant too. Trusted people sharing trusted job opportunities (to a degree). Good stuff Jared.
John -- Forrst is more for sharing actual work, we aim to be sharing what you're reading. We want it to be about the links to the stuff that matter to a developer or designers bottom line: new Google fonts, jquery plug-in, coffee code, etc.etc
Not really a job board -- but a easier way for IT pro's to share that aspect. We've had people be contacted because of their talentopoly hosted resume already from some of the big boys -- so that function is getting noticed.
The idea behind the hosting of resumes is because the goal is to have it be one of the websites you check everyday. And for designers looking for developers, IT professionals looking for designers, and vice versa -- you can qualify potential co-work partners.
