I like this app. I was recently looking for a place to host a resume, and wish I had come across your site sooner.

As everyone else has already said, your messaging and initial pitch need to be cleaned up. Personally, I would stress the sub-resume's idea as that seems to be your best feature.

I'd also add an option to incorporate facebook/linkedin/twitter profiles to a resume. I did see the share buttons, but having a direct link to the persons profile would be a good feature as well.

Best of luck.
