buzz Day 1 of Google I/O is all about the APIs, Buzz joins the funThis is our third story today just on major APIs that Google has released today at the first day of its developer conference, Google I/O. As we predicted as one of our 12 stories to watch at I/O, his time up, its Buzz, which launched in Labs along with a number of third-party developers including Tweetdeck, Seesmic, Plancast, Klout, Meebo and Boxee.

What does this mean? Well, it now means you’ll be able to view and post your Buzzes (or whatever they’re called) from a few of your favorite social media clients (Tweetdeck, Seesmic), see your plans show up in Buzz (Plancast), get your Buzz Klout score, and more. Basically, you do it with Twitter, now do it with Buzz.

Of course, keeping with Google’s very well broadcast committment to open standards, the API includes support for lots of services such as OAuth and ActivityStreams.

A robust API built into a wide range of services can only help Buzz (assuming no privacy issues pop up) and puts it on a better footing with Twitter and Facebook. However, Buzz still has a long way to go, both in terms of user adoption and developer interest, but this slate of initial developers seems like a strong start.
