If you want to keep in touch with other users across social networking sites, which messenger would you install on your computer? If you are a business user, then Skype is a solution as many of us use the tool to make cheap international calls and it can be used to message other members. However, individuals are rarely on Skype and they use Facebook or MSN to chat to other users. Worse, business networking sites such as LinkedIn encourage you to connect, but there's no facility to message or quickly contact other users.08 Apr 2009
