I only use two social network apps: Instagram and Twitter. I do browse Twitter more often than I wish I did, but I definitely go days without looking at it. Instagram is great! In some ways it’s the only social network I care about.
However, Twitter has been super important for my career. When I first joined Twitter (I am user number 44,343) it was mostly web designers and mostly filled with information or links related to web design on my timeline. I got my job at Wunderlist by jokingly replying to a tweet of a friend about a job posting they had. And yet, I feel like now it’s a super waste of time when I am scrolling through it. I will probably do a mass-unfollow of everyone soon.
