Another product that aims to simplify your digital lifestyle is launching today. Give Fuser access to your email and social networking accounts, and the website will organize all of the messages from those accounts in one place so you don’t have to bounce back and forth between multiple interfaces to handle them.

Not only can you view messages from all of your accounts together, you can also reply to them as with a normal webmail client. If you want to reply to a Facebook wall post, you can hit reply and either leave a note on your friend’s wall or send them a Facebook message. It’s quite surprising how much of Facebook’s functionality Fuser has been able to extract out of that social network’s website.

Beyond organizing all of your messages in one place, Fuser plays around with the social network data to add a little functionality. You can view a “leaderboard” of your social network friends to see who communicates with you most frequently. Friends are ranked according to how many times they have sent you messages or posted on your wall, and you can view rankings according to certain time periods. Nothing terribly revolutionary, but their attempts demonstrate how it is still possible to mash up Facebook data from outside of the developer platform.
