Wondering if we can create some kind of benchmark here: for (mainly) public communities, what is the ratio registered vs. unique users you are seeing?
About 1 month after going live with our Community we see that about 10% of our visitors are registered. How do your numbers compare? Would you expect a change of this number as the Community matures? What would you consider a good number, given that registered users clearly consume more content (page views) and you cannot engage without registering?
