Don’t know what Tumblr is? Ask your kids.
For everybody else, follow Obama’s Tumblr here. They’re using it as a way to tell a collaborative story about the campaign. Anybody can submit stories/photos/etc and a few will get picked for publication.
So while you probably won’t get any hard hitting news on this channel, you’ll be able to get a lot of personal stories about life on the campaign trail. The other campaigns would do well to follow suit.
