Research by a British anthropologist shows that the optimum number of friendships that the human brain can maintain is about 150. But that’s in the real world. What happens on Facebook where the maximum number of ‘friends’ permitted is 5000? According to social networking statistics, the average Facebook user has 130 friends. Some people have a lot more.
Ivy Bean from Bradford in the north of England became Facebook’s oldest known user at the age of 102 in 2008. She quickly started making friends and became an online celebrity. When she maxed out her 5000 friend count on Facebook Ms. Bean joined the Twitter website and continued her social networking. At the time of her death in July 2010, she had 4,962 friends on Facebook and more than 56,000 followers (including the Prime Minister’s wife) on Twitter. Ms. Bean’s last tweet was July 6 2010. It read, “Going to have my lunch now will be back later”.
