I think sometimes people agree with the posts or want to give them support?
on fb I think its different than on here.. I know what you mean though
I believe it's done as acknowledgement of the post.
Its to show support. You know, to show that, " yeah! i totally support you and i understand what you are going through.
umm.. OHHHH now i get it yeah why would they click like if they could just express their thoughts in a comment?
I always wondered that too. It's like do you like that your grandmother died?
Lol Yeah! They should have buttons like in the confessions.....
