Thanks for the feedback, and for trying it out. Was it clear that that page was skippable, and that the years experience were optional?
I will take another look at the signup process. While I want it to be quick, the onboarding process is important for people to customize their experience and find who they know, etc. Definitely needs to be quick and easy though.
I assume there was a skip button on it, but it was a terrifying thing to be hit with. Even if it maybe picked just your top five skills to ask you about and offered to let you add more with a list or something. It's probably the appearance of the size of the thing.
But some of the hyper-detailed profile options may be better to ask people to add to their profile post-registration, so you can get people into your site as quickly as possible.
