Yammer is Twitter for your company. It’s a discussion board where you can post messages to your colleagues. There is an official desktop application available (in AIR) and the great native Mac OS X application. Pity is a tiny application that lives in your menubar. Every 70 seconds it asks Yammer for new messages in your network. The little icon in the menubar will change to show there is something new to read. You can now open the Yammer website from the application menu.
Call it a Yammer notification thingy if you like. For fun? I’m easily distracted and the Yammer stream at work is full with interesting discussions… and almost all remarks are off-topic. While it’s fun to read I don’t need or want pop-up messages every 5 minutes. I hope Pity is discrete enough to show there is something to go to without taking my attention away from the task at hand.
