I'm curious .. what makes a good resume for a developer (in other words, a hacker) ? I've had one job in my field since out of college (same one since I finished) and I've learnt a lot but I have no clue how to really portray it all in my resume. If I am applying for a development position do you think the hiree will care that I have experience with SEO, building brands, etc? How does one portray it? Are cover letters that important for a development position? And so on.. I've had a tough time finding well written articles on this subject but Scoble has made some definite good points, now I'm more intrigued
