Change #1
Facebook buys Friendfeed Friendfeed.com (smaller social networking site founded in 2007 founded by a few ex-Google executives). The site was loved for its simplicity and integration of social media activities. Facebook borrowed heavily from some of their applications - such as the live feed feature. It has now been bought out by Facebook. Friendfeed.com will continue to function for now....

This = facebook will get even bigger. That is why users and business' should maintain three main - Facebook, Twitter, and LinkedIn. The small sites will continue to get swallowed up.

Newer and Innovative Change #2: Facebook Search Expanded
Facebook search will now expand to allow you to search status updates and more - up to 30 days (photos, links, videos and notes being shared by your friends and the Facebook Pages of which you're a fan).
If people have chosen to make their content available to everyone, you also will be able to search for their status updates, links and notes, regardless of whether or not you are friends. Search results will continue to include people's profiles as well as relevant Facebook Pages, groups and applications.
To search for a particular term, just enter your query in the search box in the upper-right corner of any page. Once you're taken to the search results, use the filters on the left-hand side of the page to view only posts by friends or posts by everyone.
If you're searching for a specific person, Page, group or application, you also can filter by those results.
This = be patient if you can't search updates yet. It means you have to be even more careful about what you post as a status update. It also means that you are going to have the ability to reach more people that you realize....the next social media Search Engine....will Google buy Facebook?
