I know that some companies offer promotions to people who like their page. So, you go...like it, get whatever it is that you wanted from then and then unlike. That way you aren't spammed by that company on your news feed.
Sometimes you like a page on accident. Other times you like a page, but then find out that they are just going to spam you with invites and status updates you could care less about. Other times it's just because you realize you really don't like what you liked the other day.Lol.
.........................Tide changes!.............:)As Krysanthe said, as in facebook sometimes you get curious to know what did your friend write about you or what are their opinions but the application forces you to like it and to suggest it for some of your friends and sometimes you find nothing so you go unlike it back. And sometimes someone likes pages to see the content or to write an itching comment.
I cant really gove you an answer,but what I can give you is a way to a solution, that is you have to find the anglde that you relate to or peaks your interest. A good paper is one that people get drawn into because it reaches them ln some way.As for me WW11 to me, I think of the holocaust and the effect it had on the survivors, their families and those who stood by and did nothing until it was too late.
