What’s a “social gadget”? It’s any gadget whose contents you can share with friends (which in this context means anyone in the Friends group in your Google contacts). Gadgets with social features in the initial group include news and YouTube sharing, and games like Chess and Crosswords. Particularly notable from a Lifehacker perspective is the ToDo gadget, which lets you track tasks (though unfortunately it doesn’t seem integrated with Google Tasks).
As with most Google features, the rollout is going to be gradual. If you can access the new iGoogle social gadgets, let us know what you think of them in the comments.
