It’s been a while since we’ve had an open thread. Feel free to use this opportunity to boast about your own personal math-related website.

I wanted to take a sounding of the Ars Mathematica readership, if for no other reason than me being nosy. It seems to me that we have a pretty broad readership (from Ph.D.’s to high school students), but I for one would like to get a better idea of the distribution.

Let me be the first to divulge info.

Walt, Robbie and I all went to grad school at the University of Washington – Robbie does/did Ergodic Theory, I am somewhere in the intersection of algebraic topology, combinatorics and logic, and – as far as I have been able to ascertain – Walt knows everything.

I’ve learned to take all media articles about internet phenomena with a grain of salt, but this article from news.com, Growing Pains for Wikipedia, claims that Wikipedia is changing its policy so that anonymous users cannot create new pages (they can still edit existing pages). While practically speaking it’s a small change, it’s a big change in Wikipedia philosophy. The online encyclopedia has always prided itself in the ability of anyone to edit, with the notion that making participation as easy as possible will attract more and higher quality editing.
