We initially wanted it to be anonymous but ended up going with login for two main reasons: - Social login means sharing is only a click away, encouraging conversation and possibly more thoughtful contributions. - We wanted to give people equal chance of contributing and avoid the scenario where a handful of users (vandals?) find the site before everyone else and take over it all. That meant limiting the number of marks a person can make in a given time period - and that's easiest to do when you have users. Would love to hear your thoughts on these points. This is still a work in progress after all...
