Yet another BlogChat type chat has been getting some hype lately. I've pointed out about a dozen similar chats over the last couple of years mostly due to their similarity to BlogChat that Brent Ashley and I developed in 2002. 3Bubbles falls into the same category. Brent blogged about it here.

Here is how they describe 3Bubbles:

Until 3bubbles nobody has developed a way to tightly integrated chat into the blogosphere naturally and specifically.

Blogs are communities based on communication -- posts, comments, cross-linking and trackbacks. The problem is that communication is slow. 3bubbles provides an alternative that is complementary to blogs by creating real-time dialogue between blog readers and authors in a secure and spam-free fashion

BlogChat has been doing this since 2002.
