There's a couple reasons as to why I believe that it makes sense in the platform. To begin with, the concept that started off this project 6 months ago was simply to make women more present in people's following lists. This was an entirely identity based project from that point, attempting to increase & amplify the voices of a particular group. Needless to say, with a concept set up & validated, I kept going in the same direction.
Secondly, while some of the filters of the platform are identity-based (ethnicity, gender, LGBTQ...) I also implemented multiple based on their background (low-income, migrants, language...) as well as based on their interests. I plan on expanding this group further, as I find it extremely valuable to better diversify our feeds. There is much more other than whether someone is a man or a woman, a person of colour, or a person with disabilities.
There is a third reason, one which I might not be too fond of, but thing is, in order to achieve diversity, people tend to prefer going about it through people, faces, and real identities. As a rather "private" and ambiguous person online, I've noticed how hard it has been for me to have recognition or validity, since all in all people can just judge me by my work and ideas. Had I gone this path with the platform, it would have likely failed, and I could have not contributed to solving this issue.
All in all, your idea is good in an ethical perspective, but when it comes to its implementation, it's absolutely useless, unless you change people's mindsets (very hard, specially because you also have to change some people's mindsets in terms of diversity already...). Then again I will see if I can implement something like this in the future, I think I might be able to figure something out. Thanks for your insight!
