The always excellent Social Design Notes tells the tale of a "tailored information" program in St. Louis which distributes personalized vaccination calendars to low-income parents - complete with the kid's picture - to remind them when to get their tykes which shots. The kicker? Vaccination rates have gone up 50%. A great example of a simple measure, made easier by new technologies, which improves life for people who've been having a hard time.

John's also got some good posts up about Zapatista media, the explosion of graffiti in post-war Iraq, activists and messaging, and a whole bunch of other provocative topics. If you're interested in both graphic design and changing the world and you're not reading SDN, you're missing out.
