Era of Multiprotocol Instant Messenger

Now a days people have at least 2 email accounts and most of the accounts are from different provider. When I am in my office I use gtalk for office account and yahoo messenger for my personal account. Open emails in gmail and yahoo. And might open facebook or any social networking sites. But now digsby has reduced much of these work. In one login to digsby I can login to messenger for gmail, yahoo or even facebook and more. See mail titles of various accounts and facebook feeds. And it is very intuitive and customizable.
