This is very nice! You can add it to your system, yes your system of choice and it lets you share files that automatically syncronize with any other location. Check out the demo video... not going to say much more than that because it's something you will love or not care about. I think it is clearly cool.

OK... we could talk about individual features but that isn't going to help us understand what the driving features are in the next generation features of browsers. IE and Mozilla tend to be leading the way with IE 8 and the Mozilla Ubiquity project. In a nutshell it's about user controlled collaboration. It is about the user controlling integration and information in his own way.
So, what is the point? Next generation web sites should be thinking the way next generation browsers are headed. Does your site allow users to gather information and use it in a friendly collaborative way? How easy is it for them to pick pieces of information and share in a social network of choice? We have a project on RiaForge called cfOpenSocial. Send me a message if this is something you are interested in helping get to the community as an itnegrated library running in ColdFusion. If not look at what others are doing and make sure your site isn't going to be viewed as 'anti-social'.
Yes, the next features of the browser focus on two major concepts. They focus on being social and collaboration. Of course change helps keep us IT guys working... so in addition to giving more to the users that is good for us!
This one is a new volley in getting a piece of the news channel space. Of course this will be easier for Yahoo than some others.
So, what is Y!Buzz ?
Here is a clip from the about page.
* The buzz can be about anything - a great story on a major news site, an extraordinary bit from an obscure site, an intriguing video, or a fantastic blog that shouldn't be missed.
* Instead of editors, people like you determine the top-rated stories.
* First, we determine the most popular topics that people are searching for on Yahoo!.
* Then, we showcase the most popular stories within those topics, based on activities like voting and emailing stories to friends.
* Stories with most Buzz may be published on the Yahoo! home page - you can impact what millions will see on Yahoo!.
Note... feeds are also there if you like to get your Buzz via RSS.
