Not a lot of people really understand Twitter. It's not just a replacement or an alternative for Facebook, it very much should be used alongside Facebook. As it's been said, Facebook is for people you know but don't like and Twitter is for people who you like but don't know (not completely true but quite humourous nevertheless!). I like to use Twitter mainly for new articles and comment but I found a great account to follow today which is one of the many other ways Twitter has revolutionised the internet.
James Newall (@james_newall) is the Lincolnshire Police Press Officer and he makes sure that press releases from the Lincolnshire Police Force gets to the public. This includes his latest post detailing where Lincolnites can get their bikes security marked in response to the raise of bike thefts in Lincoln and also a Crimewatch-esque call to identify a pure-thief caught on CCTV.
Some say social media is taking over the world. I don't think that is always a bad thing.
