I'm totally enamored by this group; it's the main reason why I actively use Instagram. Tons of backpackers, nomadic families and weekenders that regularly post incredibly inspiring content.
Recently I've begun seeking out and meeting some of these people in-person. No other service has supported connections like this for me. There's an honesty on Instagram: story telling, real life, often real-time that doesn't exist anywhere else.
Not that the content people choose to post isn't curated, but it seems to be less abstract. The form of expression that developed inside 140 characters is still pretty strange to me. Sharing news and articles designed for social media doesn't really give you an idea of who that person is, just like reblogging images doesn't give you any information about a person's actual life.
