another note on usability. i studied facebook and twitter quite a bit before coming up with a3m. and the reason is becuz they are the biggest, fastest growing user centric websites around. and what users are familar with is one step ahead of something new/different.
authentication is a necessary evil so it should be easy and as far as possible transparent to our users. They do NOT visit our websites with the intention to authenticate but do we at times make it so hard they end up leaving before they even started?
that's the reason why a3m is "as simple as it gets". please don't ask me to add another 100 fields to the sign up or sign in process. =P
