Google tested Google Buzz only internally, the product manager told the BBC, which is obvious, because only engineers working 80-hour weeks would think that people wouldn't mind having all of their most common email and chat contacts exposed for the world to see. follow link
Avoid Simple Typos
If, like me, you find yourself typing 2911 in place of 2011 entirely too often, you can have Mac OS X (either Lion or Snow Leopard) fix such typos for you automatically. Just open the Language & Text pane of System Preferences, click the Text button at the top, and then add a text substitution by clicking the + button underneath the list. It won't work everywhere (for that you'll want a utility like Smile's TextExpander), but it should work in applications like Pages and TextEdit, and in Save dialog boxes.
