When Twitter introduced hashtags, they were simply a way of linking individual tweets to a particular topic. This year, the hashtag has taken on a life of its own and trending hashtags have been a way of finding out some of the years biggest events, as well as what Londoners had on their minds throughout the year.
Within a couple of clicks, anyone can see what the top ten topics are that London, the UK and even the world have been tapping about. Yet, more than just a social tool as well, Twitter has morphed into a business platform, a useful news source and even the place to be for breaking stories.
