Just like Google and Facebook, Twitter now charges brands to reach their own customers

You know a web service has reached massive scale when it can charge brands to reach their own customers. Google has been doing it for years, Facebook’s been at it for the past couple of years, and now Twitter has just entered this hallowed territory with its new promoted tweets feature, which lets brands keep their tweets alive in your stream only if you have already followed that brand. The irony here is that you are only seeing these promoted tweets if you already followed that brand – so the brand is paying to advertise to users that already like it.
