1.Facebook
Number one on the list is Facebook. Well, this is really not surprising at all because if you are going to make the number of users as the sole criteria in judging the best social media sites, Facebook will really turn out to be the victor without further deliberations. Currently, it has some 700,000,000 registered users, each could be active or inactive, but the thing is that 700 million is a very big number. Facebook really never fails to impress it subscribersbecause of the regular updates and maintenance checks that they conduct from time to time.
