Having originally started with a relatively humble photo sharing app, Instagram had morphed into a massive online community even before Facebook bought it, and now it's the place to go if you want to share that cute cat picture, especially if you want to then share that across multiple social networks. The problem with Instagram though, and it's a problem with all social networks, you find yourself checking it far too often, and that starts to get annoying for other people. And we're all guilty of it.
