Google creates themed communities around the search service
On the one hand, Google
On the other hand, if you are not registered as an expert, then as a regular user you can only "subscribe" to the services of this "information provider", which is a group of experts. You will see which web pages and which websites this group considers the most interesting and worthy of attention. User groups are thematic. Already there are medical and tourist associations , as well as information and news communities .
You can include an unlimited number of providers or a single person in your list. When millions of such connections are established, it turns out that on the basis of Google thousands of ramified social networks are created, closely intertwined with each other. All users will be able to mutually influence each other's search results and, thus, further strengthen their social ties. It turns out something like vertical search engines, which are created and maintained manually. Basically, the idea is not new. The well-known foreign service Rollyo offers approximately the same thing . But there’s a slightly different approach: each user can create his own virtual “personal search engine”, and other users can use it right now.
