There is no doubt that the Internet has changed the way that millions of people communicate with the outside world. And there is a lot of buzz and activity around social networking. One of the most interesting opportunities which arise from this is lifestreaming.

When people hang out with friends online, they talk about music, review movies, share travel stories, exchange photos and discuss video games. And they chat about life and recommend books as well.

Lifestreaming is an online record of a person's daily activities. It will allow you to climb inside the head of someone. And you can also experience their day through a digital collection of public text messages, blog posts and photos. What's more, thanks to mobile broadband(宽带) and tiny video cameras, you can also watch a live video stream of them as they move around their world.

Lifestreaming offers the ability to store and broadcast this information exchange. People now can create，collect and publish their interests and activities. They are creating content that reflects their life.

Generally speaking, the lifestreamers have been broadcasting their lives 24 hours a day. Facebook havs now made it possible to load all these other Websites directly into your Facebook profiles. Now users can display their blog posts from their blog. They can display the drunken pictures that they uploaded. The embarrassing videos they have from their YouTube profile can also be shown, and so much more.

Lifestreaming is the newest way to let your friends know what you're up to, and you needn't force them to follow you across many places. Not everyone is into lifestreaming, but it is one of the hottest areas for development out there. And there are a large amount of services offering a way to collect all the little bits of your online life，

Life streaming might be described as a variation of microblogging, because they all focus on the brevity(简洁) of content. But you cannot ignore the difference between them. With microblogging, you write messages directly within the application itself－as you might send a text message. But with lifestreaming application, you collect your other content from around the Web and arrange it into a single stream of short bits of information.

With lifestreaming, people now can learn more about people they trust. By selectively following lifestreams, people are changing how they get information.
