Humans TXT is an initiative for knowing the people behind a website. It's a TXT file that contains information about the different people who have contributed to building the website.
But who is actually using it nowadays?
Build with Chrome: http://www.buildwithchrome.com/humans.txt
The Guardian: http://www.theguardian.com/humans.txt
And lots of others. So why shouldn’t you, right? Eventually, it’s all up to you. We just give you to options to make use of it. So you don’t have to if you don’t want. Like Humans TXT says: “The only aim of this initiative is to know who the authors of the sites we visit are.”
