KonahaANBU said:twitter is irrelevant when it comes to facebook vs google+ as twitter has its unique style of trends and hashtag search, posts(tweets) of only 140 characters , gif support (which fb lacks), privacy settings only limited to followers (here fb and g+ have advantage as they provide better customization in privacy settings), time oriented timeline or news feed instead of system oriented one in FB and may be G+. (Displaying those post that have more influence on yo first on FB)
How is facebook different from twitter?
Sorry but I don't know much about social media sites.
