Facebook started a new concept of copying other websites to enhance its features. The users can now post their “Status Updates” just like Twitter allowing them to tell their friends what they are doing at any point of time. So Facebook has copied or imbibed a feature similar to Twitter with a minor change enabling the posting and reading with status updates via SMS. It’s a move that kills off any possibility of a link up between the two. Google and Yahoo are most likely to be interested in buying Twitter these days. Yahoo would most likely buy it because it’s cool and then recently it failed to acquire Facebook. That said, Yahoo is currently ahead of Google when it comes to interest in expanding to big social media networks.
