Facebook vs Google+
Number of people talking about your facebook page will decrease and your posts(links) will reach to few people even the fact that you might have thousands of fans. I have a facebook page with 15000 fans and i get less than 100 visits from each post.
Different people have different views, but i think that Google+ is the best option as if you are login and have liked a Google+ page. Its post will appear on first page of google search. And for bloggers i think Google is the most favorable choice as Google gives no value to Facebook posts in search.
