We require that people join because many of those who join like the service and end up contributing back to Quora, which makes it better for everyone. People spend a ton of time making Quora great by sharing their knowledge on here, so we think it is reasonable to ask that others who want to get to all the free knowledge here take the first very small step toward contributing back which is creating an account. That is the only reason we have the policy: to get more people to join who will share more knowledge and make Quora even better for everyone in the long run.
The community at Quora is pretty good, so they seem to know what they're doing.
