Rating now optional?

I notice in the latest incarnation of Duolingo that rating translated sentences now seems to be optional. Wasn't rating part of the original crowdsourcing genius of Duolingo? Was it found to be unnecessary for every user to rate translations? I really like that there are now three sentences given for rating. Being able to compare them is good.
