If This Then That (www.ifttt.com) is an intriguing new service for managing and integrating social media. It lets you specify simple rules of the form:
if <this event> then do <that action>
...where <this event> may be something like arrival of an email, a local weather forecast of rain, or a new blog post on Tumblr, and <that action> can be something like send an SMS message or an email, or post to EverNote or Facebook.
