Internet.org by Facebook "provides free access to basic internet services to a billion people all over the world." Their goal is to make the internet available to every person on earth, starting by making certain websites available with no data charges in many areas. The goal of Stack Exchange is "to help the most people we can."
I believe a partnership with Internet.org would help Stack Exchange accomplish its goal of helping as many people as possible by providing access to those who would otherwise be unable to access the Stack Exchange network. Internet.org allows site owners to submit their site and doesn't charge the site owners anything.
There are a few conditions to being part of the program, but I think Stack Exchange is probably meeting them already:
Explore the entire internet
The Internet.org Platform aims to give people valuable free services that they can use to discover the entire wealth of online services and, ultimately become paying users of the internet. Services should encourage the exploration of the broader internet wherever possible.
While Stack Exchange answers aim to be self-containing, they also frequently reference external sites that give more detail. I think this meets the requirement of providing value alone while encouraging the exploration of other sites.
To sustainably deliver free basic internet services to people, we need to build apps that use data very efficiently. Operators have made significant economic investments to bring the internet to people globally, and Internet.org needs to be sustainable for operators so that they can continue to invest in the infrastructure to maintain, improve and expand their networks. Websites that require high-bandwidth will not be included. Services should not use VoIP, video, file transfer, high resolution photos, or high volume of photos.
- Some sites are image-heavy. Sites with many images would probably not be suitable for the program. Participation in the program could start on one site, possibly Stack Overflow, and other sites could be added over time.
- Embedded content from other domains is removed. We'd need to get cdn.sstatic.net and stack.imgur.com whitelisted as part of the submission.
Would Stack Exchange consider investigating a partnership with Internet.org as a way to broaden it's impact by becoming available to people with limited internet service? I think this could be an awesome partnership!
