This is quite interesting... but can I suggest you try to sell why you'd want to go Pro? There's a button that says "Go Pro", but there's nothing that explains what extra features I'd get with an upgrade.

There's a link that says you can import your LinkedIn profile if you go pro - as a suggestion, add a link to the other reasons why you should go pro (I don't use LinkedIn).
