Nsyght is a web application for Twitter and Facebook that lets you search information from your friends in real time, post directly to your networks as well as search and filter your own "personal fire hose" of information. You might remember Nsyght as a bookmark based search engine from when I wrote about it back in 2008 . It was down for some time and is now reborn as a web client that allows you to aggregate, share, and search your social graph in real time.
