Digg, as you likely know, is the most popular of the social media sites -- that is, sites where users identify the most interesting and newsworthy tidbits, and then vote on which they like best. I check "Top in 24 hours" area of Digg many times a day to see what interesting, funny, pointed, or poignant news items, images, and videos are connecting with the popular mind. If you're a fan of Digg, you'll be happy to note the launch of Buzzwire earlier this week — sort of like Digg for the iPhone and other mobile devices. Like Digg, you can submit and vote on your favorites. You can view the most popular 20 items or browse by category. You can also keep a list of stories you want to read later. There's also a social networking component, like other such sites, that lets you connect with friends and see what they're reading or watching. To access Buzzwire, point Safari at m.buzzwire.com.
