"+1" and "Like" on the Chrome panel

A couple of days ago, a new extension appeared in the Google Chrome extension directory, whose potential may be promising.

It adds a “+1” button to the browser bar, allowing you to share any web page in just one simple click. As in the case, if you clicked the “+1” button located on the site, readers of your Google+ feed will find out about this and ... of course, the search giant itself. Theoretically, such a function can be a powerful tool for enhancing the influence of Google on the social networking market, especially given its promises to increase the value of “+1” votes for ranking sites in search results.

Today, Facebook developers responded to this initiative by releasing a similar extension with the “Like” button. In the same way, it allows you to click "Like" on any webpage using the button on the Chrome browser panel.

When surfing the web, both extensions show the number of people who already liked the page you are on. In this regard, perhaps the most curious here is the question of privacy. It follows from the agreements that both of these extensions send all the addresses of the pages you visited to Google and Facebook respectively.

Social networks are developing, and if earlier their users were interested in what a person loves, what music he listens to and at which school he studied, then now everything is moving towards the realization of another interest: what page he is looking at at the moment. So far, however, only if the viewer wants it. But maybe just for now?
