Buzz has been building about real-time search. Of course, you can search real-time Tweets on Twitter, Facebook is testing search on its live Feed, and Bing just added limited Twitter search to its engine.

Now, FriendFeed is launching real-time search and it has the potential to be the mackdaddy of them all.

Here's why. FriendFeed is a social aggregator. It's a one-stop shop to check and update a bunch of different networks, blogs, etc. Now, you can search all of that in real-time.

The drawback? It only searches what people submit to FriendFeed. Whoever does that can basically say "Check" in the chess match of social real-time search.

Still, this is a tremendous step in that direction. Even better, FriendFeed has released an embeddable real-time search widget you can put on your website.
