While strolling on that inter-network thingy, you quickly realize that there’s one mandatory identity certificate required: your email address.
It is not possible anymore to be active on the web without an email address. Most services require that you provide a valid email address. And it’s a good thing because email has the following properties: being decentralized (not tied to any provider), being standardized and freely implementable, being easy to share (just one human-readable string). It’s also possible to have multiple addresses, meaning there’s no enforcement to have a one-to-one connection between a real-life identity and a web identity.
But, now, there’s a increasing need for a more complete web identity. People want to know your profile, want to talk to you, learn about you. That’s why more and more services are allowing you to connect with your Facebook or Google account.
Is a Facebook account a good web identity? My French speaking readers know that I don’t like Facebook. What’s the biggest problem of Facebook in this context? It is centralized. It is tied to one and only one company. It is not standardized. It cannot work. It, hopefully, should not work.
