Prokofy Neva has another post on Twinity on the Second Life Record. I think most of the observations about functionality are very fair, and we are working on making sure that the naming thing is clearer in Twinity. In fact, now you can change your display name through www.twinity.com. Other technical challenges are natural for us given where we are, early in our beta. We hope that we will be able to keep improving Twinity for you.
