Tracking friend’s activities across social sites like Bebo, Digg, Facebook, Flickr, Hi5, imeem, Last.fm, LinkedIn, MySpace, Pandora, Slide, StumbleUpon, Twitter, Windows Live Spaces, Yelp, and YouTube, is of course another sign that we are all social and our social life is increasingly getting shifted to internet. Spokeo and FriendFeed are the two main social network aggregation services doing the heavy lifting task of tracking. The question I have is that do they simplify our online life by pulling all of the content into one centralized monitor or it adds to the complexity

Here are some comparisons points:-

• Spokeo is little harder than FriendFeed to bring friends accounts together if friends sign up for online services using multiple email addresses. FriendFeed has also this nice feature of setting FriendFeed RSS feed which can then be handed to all contacts.

• Spokeo is also largely a one-way tool - you can reply to and share updates, but only via email to the contacts. FriendFeed lets you share content from 28 different services via a single stream, and subscribe to the streams of your friends.

• Spokeo is very simple to set up- it can take in directly all of the contacts from Gmail, Yahoo, or Hotmail, and then go out to the 30+ sites it monitors and bring back any new content from people in your address book. In comparison, FriendFeed is more complex- it takes in Facebook friends, but only the ones who are also FriendFeed users, plus each member must specify which sites he wants to expose to others.

• FriendFeed publishes all of the activities in an endless stream which includes all of friends’ (including those who decide to make their content public) content-bookmarks, blog posts, status updates, pics, and videos. Spokeo’s appeal is to keep track of interesting friends who are prolific across the Web.
