Hello,

I am a fan of Google, like your product very much!

I have a rough idea about Location Based Voice Advertisement which incorporated into the Google Map/Google Music.... If the user take  the mobile device and listen the music on the street, the voice advertisement from the intelligent server pushed to the device timely. 

The mission of Advertisement is to attract the user's attention, spread over product information. However, for the mobile advertisement, most of them need user to open the device to read. We can call them vision advertisement. But in some cases, for example, driving a car, you cannot read.  So I think the voice mail is significant.

Saw this awesome boat in this month's Southern Boating.   Did you ever think that spinning Google+ off as a publicly traded company with  a new name and a new image might be the resolution to trumping facebook.  A new name--try a contest with video submissions on why you think your name is best.  Toronto did this to come up with "Raptors" for it;s basketball team. Winner gets a chunk of shares in the new spun off CO.  Your public buys shares  in the new named social network company.  Company pays a Q'ly dividend, but not in cash.  Dividend is paid in some sort of social media capital.  Think about it this way.... If facebook were yoursm, what would you do next to cannibalize it?  ...Love that boat!
