Thanks. What would be your preference and why? With our 1st version we want to learn from our users, so feedback is more than welcome :)

I don't use services with a Facebook login. They know enough about me as it is. Regular local logins should be an alternative.

I don't use Facebook, but I understand that a lot of people are uncomfortable with meeting random strangers from the internet unless they've already posted a lot of information about themselves online.

Regular logins were once popular.

I think social login is fine as long as you give people a bunch of options (twitter, gmail, fb etc) If you give one option at the beginning it should be non-exclusive

Go see how Reddit did their registration. You don't even need an email.

This is more like AirBnB than Reddit.
