While I have a somewhat dim view of niche social networks (seriously, I just joined a Trekkie-only social network, why the heck does that exist?), I'm going to give this a try, it sounds interesting.
My initial feedback: The signup process is horrific. Asking me how many years of experience I have with each skill someone on LinkedIn endorsed me with? Literally just delete this entire page of the process.
Signup should be simple, you want people using your site as fast as possible.
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.
