Interesting. What are the main features / benefits? That it's serverless, is one, are there other things too?

What's your motivation, what's the reason you're building this :- )

Feedback: Privacy problem, I posted a comment, and this then appeared as my name and comment:

    myemail - NaN-NaN-NaN NaN:NaN
    
    Test of https://github.com/metrue/YoYo

having specified `[email protected]` as email address.

That means YoYo in practice gives away peoples email addresses, when YoYo uses `myemail` as the username — most people use well known providers like `@gmail`.
