I think the random string is clever. My first instinct would be that you should be able to reach it at http://resume.io/dangrossman http://resume.io/dangrossman

I think the random string is clever. My first instinct would be that you should be able to reach it at http://resume.io/dangrossman http://resume.io/dangrossman, but then if someone is familiar with the service they could circumvent the tracking URLs. On the other hand, having a human friendly URL might be nice in the long run for easily finding people. Definitely a tradeoff.
