Article about Google Buzz

Hello,

I have to write a plea (I am not sure wheter it is the right word for the dutch word: "Betoog", so I used Google Translate to find the word.). Could someone please review it and give some suggestions how to make it better? If you find errors, would you please give the grammatical rule why it is wrong?

Thank you for your help, I really appreciate it!
