This social network offers the cool photo effects of Hipstamatic powerfully combined with the social seduction of Facebook, the popularity filter of Reddit, the hashtag and follower sharing models of Twitter, and the curse and blessing of commentary on YouTube - and that's just within the app. Instagram makes your photos and videos look cool and then makes it easy to share them instantly, across multiple platforms, allowing you to broadcast how #awesome your life is right now. The competition for cool can get a little tiresome(the comments are full of users seeking followers), and we'd love to see more moderation for photos and comments to be totally safe for kids. As with any social network, it's helpful to talk to kids about privacy settings and mindful sharing, since things shared on the Internet can follow you forever. Overall, Instagram does a remarkable job of implementing a neat idea with an easy and fast interface, all for free. Instagram is a popular photo- and video-sharing app that requires only a couple of touches to produce retro-looking projects and then share them with friends and other Instagram members. With recent updates, the app adds video, letting you add filters and post to your feed much like you do with photos. It also got a new way to adjust brightness and contrast in the most recent update with a new Lux slider. But what's really special about the Instagram phenomenon is how users have used the app to create a story about their everyday lives through stylized photos and videos.
