I got my username choice email today for Openbook. I doubt its still available, but I am going for @ Matt. (no space). Otherwise I will be @ MattMoore. It does appear that Openbook will be a bit like the old G+, circles and all and Alpha access looks like it will happen sometime in the next month (They say March in the Indiegogo, but yesterdays update says differently), so enough time to evaluate even before Google's early departure. I was beta for G+, and remember the experience of meeting new people, integrating existing technologies in new and fun ways, etc. I suspect that will be my experience with Openbook, and I encourage everyone to check it out. https://www.indiegogo.com/projects/openbook-it-s-time-for-a-better-social-network https://www.indiegogo.com/projects/openbook-it-s-time-for-a-better-social-network
