I love the idea behind being able to collect the snippets and quotes you come across, but not having an alternative for a Facebook sign in pretty much makes this useless for me.
Agreed. I think this would be very useful in a business context as well, but business users need an alternative form of login. In the end I ended up to our B2B web app directory anyway though: https://starthq.com/apps/quotered
Sorry to hear that - we'll work to introduce an alternative to Facebook login in the near future
