Here is their description
"Miramir will soon become an alternative to Facebook, as well as other networks, and it is aimed at the privacy fighters and change makers, activists and advocates, yogis and vegans, meditation enthusiasts and sacred geometry followers, preppers and alternative news readers, raw fooders, vegetarians and health conscious individuals, urban gardeners and alternative technology lovers, the kindness deeders and peace promoters of the world. All the great people of our earth who care for our planet, people, and future as a human race.
The really groundbreaking aspect to Miramir is that it is much more than just a social network. It is a Facebook, Ebay, Reddit, Quora, Meetup, Craigslist, Plenty of fish, Kickstarter, Airbnb, and a lot of other networks combined into one. Except with a big difference. It is focused on privacy, freedom of information, world changing ideas, global consciousness, community, interconnectedness, and a healthy future of humanity which we all want to be a part of."
