To all those asking "What is Yahoo?" ad nauseum, can you answer the corresponding question, "What is Google?" ?
And once you've done that, tell us how G+, Picasa, GAE, GDrive, GMaps, Android, etc. fit into this definition?
Er, I thought it was pretty well known that Google is an ad company.
G+ = Consumer profiling
Picasa = Get people sharing their photos on G+ (Now with tagging!) so that they can be profiled
GMail = Consumer profiling
GDrive = cannot tell since they insist on showing the pages in Japanese despite my browser telling them otherwise. But I wouldn't be surprised if they analysed your files for profiling (cannot read the japanese TOS to tell.)
GMaps = Location based advertising, consumer profiling
Android = Muscle in on mobile advertising and consumer profiling
Almost every one of their services can be tied back to "How can we improve our profiling of consumers so that our ad-networks are more effective"
Thanks!
