It’s titled Myrl – Social Networking over Virtual World boundaries and shortly summarized goes like this:

• Connecting virtual worlds is not entirely true. You’re connecting the residents through a networking service, not the virtual worlds.
• I think measuring in-world time to determine someone’s karma too, is a great idea.
• I already have a blog, youtube account, flickr stream. Let me set up links or aggregate (Flickr Api, Blog Feed, ...) please, because I’m not going to upload, tag etc everything twice.
• I can’t find the ‘invite friends over’ button. Which is rather strange for a social networking service.
