TimesPeople (FAQ). It's an NYT app (a Firefox add-on) that you can use to "create a network of like-minded readers." You add friends and it adds a social networking bar to the top of NYTimes.com. There's also a Facebook app. Some people will likely criticize the closed nature of this, or the "do I need another social network?" aspect, but I think this is a smart move.
