Really nice little tool from facebook mimics Google trends. However the facebook one analyses comments and wall posts across the entire facebook platform.
Shows the command facebook have over their data. If they are able to develop this further we will be starting to see targeting of their ads getting tighter and tighter.
Already we expect to be able to target web users based on the interests they have implicitly shown by visiting particular categories of sites. Soon I'm sure a network will find a way to link information with sites like facebook.
It isn't far way at all as Drive are already offering a combination of targeting through linking their network inventory with your messenger \ msn profile. This is a very effective development as the infomration contained within the msn profiles has been shown to be quite true.
Yahoo's purchase of Blue Lithium means that they will probably find a way to copy Drive and implement the same kind of targeting based on Yahoo profiles.
Imagine what would be possible if one of the social networking sites went out and bought a network - facebook's user data being exploited across the internet!
I think once the general public know the extent of the data we use, there will be a small outcry. Although debates are being had about the ways in which we use personal data, it does seem to have gotten to silly levels.
