All of us knew that Facebook had a limitation on friends. It was 5000 friends. I think last year they put a new limitation. And now the sum of the friends and likes on fan-pages should not exceed 5000. I had exceeded it. And limiting fan-page likes is not a good thing as I think. Some times person could have 4000 friends and he also like 2000 artist, actors and businesses. But Facebook will not let him to follow his fan-pages and all the friends.
Google+ also has limited to 5000. I don't like anykind of limitation. I want to be with so many friends. Please don't limit.
