Diaspora
What is Diaspora?
Diaspora is a federated social networking service, designed to be a more privacy-aware alternative to 
Facebook . Share what you want, with whom you want.
Diaspora lets you sort your connections into groups called aspects. Unique to Diaspora, aspects ensure that your photos, stories and jokes are shared only with the people you intend.
Diaspora makes sharing clean and easy – and this goes for privacy too. Inherently private, Diaspora doesn’t make you wade through pages of settings and options just to keep your profile secure.
It is based on
Ruby , 
Ruby on Rails

- rustyknight07 reviewed DiasporaruI created an account and before I'd even entered any information into my profile I got a message asking for money. Nowhere on any of the websites recommending Diaspora does it mention that you are expected to pay to use it. I deleted my account immediately - descriptions need to be updated so that people don't join and then find they also have to pay.

Diaspora* main strength over Minds.com is that Diaspora* is really fully decentralized (distributed and federated). Compare to Minds which is NOT yet fully decentralized. Open source code is not to be confuse with decentralized.
By decentralized ("distributed" and "federated") I mean with Minds everyone’s data is being stored into ONE huge CENTRAL servers owned by a ONE large organization. Compare to Diaspora* which stores everyone’s data on MULTIPLE INDEPENDENT servers (“pods”) all over the world. You simply choose which pod to register with, and you can then connect seamlessly with the diaspora* community worldwide. Thus Diaspora is much safer and more robust.
For those not familiar with Diaspora* you can read more on this Wikipedia article

I found this social network very interesting, I like its audience, it is at the reach of all, it is a real alternative to facebook and co but opensource
Very open, so opensource anyone can contributed in different ways to the project
Public level it is anglophone even if thanks to framasoft its opens much to French, a good community
From an idea of Aaron Swartz away from facebook marketing

The main idea to share with who you want and make groups from starts, with "aspects" , after years, the way is distributed, simple and clean layout makes this social one of the top.
It's years that exist and with low numbers of followers, because it has no marketing.
I will promote as far as I can.
Free distribution of content without censorship.
Good concept, but some functions still needed:
Great cumunety - free to choose - no company/country can shutdown/blick the whole network. Your data is owned by you
