social networking stories

Have you checked out the military's own versions of Facebook or YouTube or Wikipedia recently? No? That's probably because they're heavily censored and restricted, which is just what you want with social and crowdsourced media, and this is why the Pentagon now wants its own version of Reddit, called Eureka. Makes sense, right? ...Right?
When sharing something online, I often face the ambivalent choice of whether to post it on Twitter of Facebook. With Twitter you can reach more people but it only supports linking, whereas a Facebook update can have pretty embedded photos and videos. Yesterday Twitter rolled out some new features, however, that make the two services more alike.
