"I’m definitely not going to list out every social network and social media tool, but I do want you to understand a bit about HOW we’re using these tools, so I’ll mention a few.

MySpace or Facebook - Not just for kids any more. The grown-ups I know use both of these services for roughly the same thing: connecting with people they already know and making some new connections.

LinkedIn - Business social networking, and the top of the heap. It’s getting a little more interesting, because of their status stream, and the redesign.

Twitter - Not everyone’s on there, but we’re more on there than Pownce and Jaiku. Why? It’s not because it’s better. It’s just because we’re all still there, because it’s simple, because it solves a lot of needs.

Flickr - We’re sharing photos on Flickr and SmugMug.

YouTube - We’re sharing video on YouTube and Blip.tv and a few dozen smaller places.

Digg - We’re getting news from Digg and Reddit and SlashDot, and there are lots of new upstarts for specific niches. We seem to like these sites because they let the crowd vote on what’s newsworthy to US as a niche."
