Filtering networked media is becoming more common. Social media is often critizied for being noisy, so filters have been developed to avoid the clutter of information to make networked media more personal. Like “The Daily Me” stated, the power of a free society gives people the power to filter out unwanted material.
Facebook actually builds their network in a way that increases noise (news feed). To solve this problem, go here http://www.facebook.com/bookmarks/lists, then create a list, and add names to the list.
Twitter lists are a wonderful way to segment your Twitter network. Create your lists, Then the next level is to start a Hootsuite or Tweetdeck account and search for keywords within those lists.
Google caught on that users want to filter, so they built it into their site. Simply utilize the circles function in a similar fashion as you would Twitter lists or Facebook lists.
