DonorsChoose

Part of joining the blogosphere is apparently a chance of doing some good, in the real world out there, and not just babble incoherently about abstract nonsense. So, if any of our readers is so inclined, we encourage them to contribute to the DonorsChoose challenge, which is an annual fundraiser supporting public schools in the US. One easy way for our generous readers to contribute is to visit the page set up by our friends at Cosmic Variance, and choose to contribute to one (or more) of the worthy causes listed there.  If you need more variety of good causes, Chad from Uncertain Principles also set up his own challenge page, and he is offering some rewards!
