This year, like others before it, was a year of highs and lows on Twitter. The platform is a true digital stream of consciousness, a fire hose of collective outrage, celebration, activism, jokes and sorrow. From larger-than-life pop stars to ego-maniacal pharma CEOs to everyday users, Twitter gives everyone an opportunity to go viral and leave their mark on the culture of the internet.

So many voices contributed to the highlights on Twitter in 2015. Below is our pick for the best tweets of the year.

Here's hoping for lots more great Twitter moments next year.
