Facebook, arguably the most popular web service today, is a social site. But Facebook with all its security issues aside, one will notice that many of popular web services these days have a social component. Some examples of such web services include YouTube, Flickr, and even Google’s web search.
Visit just about any online service today and you’ll likely see a comments section or at least the most popular social sharing buttons. Of course, they all also have their own versions of the Like button, ranging from marking stuff as a favorite to voting interesting posts up. Some even have a system for voting things down.
When it comes to Google’s web search, the social component may not be as obvious in the sense that they don’t directly engage users. But if you are logged into your Google account while searching you’ll notice that Google will show stuff that are tailored to your interests as indicated by the stuff your social network (on Google plus) visits and likes.
So it seems that there is no escaping the fact that the Internet is getting more social despite privacy concerns about sharing personal stuff over the internet.
