No ToS, no privacy statement, nothing. Who are you?
Also:
1. Can I mark my account as hidden until I want people to see it?
2. What will you do with my data? Note, with LinkedIn it's pretty clear what they're going to do from the get-go just because of the nature of the service, with this there's nothing. Are you going to sell my details to recruiters? If so can I opt out? Do I have to pay rent if I do? Note some people won't care (perhaps a lot), this community is a bit of an outlier when it comes to privacy concerns.
3. What domain will I have, can I use my own?
4. Can I change the default style (as the example isn't really to my tastes)
Edit: One last thing, a full size example would be good too. You must have your own?
