I would love to try this. I would hate to have to sign in with g+ only.
That was an attempt at not having to make people sign up and make it super low friction. So an option to sign up for a different account is preferable? Also curious as to your reason for not liking that?
Low friction sign ups that require just an email address and pw are preferable to me. I use disposable emails unique to each site and besides remembering passwords, I don't worry if one site gets hacked because they won't have access to any others.
