(TED’s on its annual two-week vacation; during the break, we’re posting new playlists from the TEDTalks archive.)

Chances are, you live a plugged-in life. We connect with Facebook, share through Twitter, watch on YouTube, learn from Google. Today’s playlist explores what it means to live online.

She talks about finding community, relationships and a healthy dose of narcissism in the blogosphere:

Clay Shirky encourages the world to spend its trillion-plus hours of free time making cool things online:

Evan Williams shows how 140 characters can give voice to natural disasters and thirsty plants — and maybe change the world.

Kevin Kelly marvels at what the web has become in only 5,000 days. What should we expect from the next phase of its life … and how will we keep up?
