Around the time Google introduced their social offering called Google+, they started an exercise of bring together all their products and services. They started with redesigning all their products to bring in visual uniformity. They also introduced Google+ integration in YouTube, Gmail, Google Reader and more.
But it has also raised some questions on what happens to the data and how Google will deal with it.
What could be the advantages for Google?
Google will also integrate all the data, users have across all their products and services. This could be something that it already does through various privacy policies, but now will do it through a single one.
Users might not like the idea of their data being integrated from various other services, but it will probably give Google better way to serve up relative advertisements.
I think most people would be fine with this data being integrated, except with Gmail. People already do not like the idea of advertisements being served up on Gmail. If they see their data from Gmail being used to serve up advertisements on their search results, it might cause some criticisms of Google.
