We need a simple and professional design without looking too corporate. Add a little bit of eccentricity, fun and quirkiness to the design.
The design should definitely be Web 2.0 (even though we hate buzzwords ...)
The design should accommodate developers blogging about cool things they do by means of small feed on the home page.
Please ignore the logo from our existing site and design a new logo.
Open clean design with lots of white space. Don't box in elements with too many borders.
Big bold fonts where appropriate.
Don't use abstract background patterns.
We are big fans of 37signals design and how they put their message across.
