And with the increase in the number of claimants to social networking site Facebook Dislike button was included on the official site that shows some of the things in this regard and is exactly what Marc zokirbirgh in particularly effective early this month.
Mark zokirbirgh said in the statement that the Facebook team thinking seriously on the issue of adding a new button similar to the impressive Like button but instead denied that the Dislike button because officials felt that this button is helpful, but in return, the developers of the site think button replacement for Dislike.
