You can say a lot in under 140 characters. Twitter co-founder and CEO Jack Dorsey wrote his first tweet (on @jack) 10 years ago on 21 March, 2006 — since then, Twitter has been the go-to social media platform to get news and opinions out, fast, and easy. It's amassed over 300 million active users, and has built communities around world events such as U.S. President Barack Obama's first presidential tweet, the Sichuan earthquake and Michael Jackson's death. Hashtags have both united and divided users across social and political issues — remember #lovewins, #JeSuisCharlie, #BlackLivesMatter and #withMalala?

It's also led creatives to tickle some serious funny bones. Some of the most hilarious Twitter accounts are parodies of influential personalities such as the Queen, Bill Clinton and Lord Voldemort. You'll be surprised — amid the cheekiness, the offensive retorts and the downright crudeness, there's always something to learn.
