Facebook is also an Internet social network, created before Twitter, but focusing on a similar idea, which is posting messages on a website for all your friends to see. Facebook is responsible for neologisms like ‘to friend’ or ‘to unfriend’ somebody. The difference between the two social networks is that Twitter limits your message to 180 characters, whereas Facebook has no limit for data. A Facbook user creates their own website and posts photos, notes or even movies for everyone ‘friended’ to see and to comment on. For example, Obama has posted photos from his vacation or his family recipe for bean soup on Facebook. More importantly, Obama has a direct link on his website, enabling visitors to instantly donate money to his campaign, which has proved vital during his campaign. Linguistically, Facebook offers space for longer stretches of text, but its level continues to be colloquial.
