John Baez's protoblog This Week's Finds in Mathematical Physics is about quantum foundational issues this week. It contains a discussion of some of the ideas that people working on the boundary of quantum foundations and quantum information have been thinking about.
I'm mentioning it not lest because he cites some of my recent work, which I consider a great honor coming from the foremost physics protoblogger. My other posting ground "Quantum Quandaries" is actually named after one of John's papers, but fortunately he doesn't seem to have noticed yet so I am safe from being sued for the timebeing.
