I agree. I am a total facebook user but I am beginning to take a second thought to the idea of giving my whole friend list to random companies (which is what the sign up page offered).

I decided not to sign up because I just don't want to give that information out to every company that asks - especially when that company doesn't even respect me enough to offer e-mail sign up.

It's like - yeah, if you want to verify my identity through facebook's API, great. It's fast and you trust facebook. If I choose to save time and do that instead of email sign up and it is my decision, that's great. But why do you need access to my friend's list? And not giving me the option of using my email means you aren't really looking to protect me as a user... which means I definitely am not giving you access to my friend's list.

I use facebook every day, but that doesn't mean I want to leak my complete friend list to every site on the web.

Hi, Christian from Platzi here. You're right, we'll update to include an email login option for future courses. Thanks for the feedback.
