Selling stuff online isn’t new. But for teens and young people, eBay, Gumtree and Craigslist are outdated. Instead, Generation Instagram has discovered Depop – half social network, half shopping platform, which lets users upload pictures of stuff they own, to sell directly to others. Depop now has 11 million users – three quarters of them are under 25. And if you’ve got a popular store or are featured on the explore page that’s curated by Depop staff, the platform can turn into a steady source of income. Founded in 2011, Depop was one of the first apps that brought buyers and sellers together directly. It’s not the only app of its kind, there is Vinted, Poshmark (currently US only), and ThredUp which are based on similar concepts, but each is trying to carve out its own niche. Some allow you to list designer clothing only, while others don’t have an app but rely on web browsers. Read more at Wired.
