“Summertime, and the livin’ is easy,” sang Ella Fitzgerald, making absolutely no reference to developments in social media. Quite a glaring oversight, as there have been a number of interesting milestones this summer. Instagram Stories now has 250 million daily active users, while Spotify hit 140 million monthly users. Katy Perry tweeted some stuff, and we liked it, as she recently became the first person in the world to reach 100 million followers on Twitter. What else has been going on? Lots. Pull up a sunlounger and let us cast our rays of social media goodness upon you.
