What's the fuss about Phoenix?

Great knowledge.

Best talk on the conference so far

Best talk on the conference!

Excellent talk!

Epic presentation and superhuman ability to do a live demo & coding all while talking without hesitation and insecurities.

I wished I could have seen the examples of interaction and / or embedding of a 3rd party module (different language, runtime, service or whatnot)

Tempo of the talk was very fast but the speaker's audibility, expressiveness and good english made it really easy to follow. Live demo + coding + mastery of the subject is always a win in my book.
Also, answers after the talk were clear and unequivocal.
Personal favorite, great stuff!

Mindblowing.

Really interesting topic. Great skills from the speacker for speaking at such a speed while being still very clear

Amazing talk. Amazing speaker.

He was speaking so fast (but very clear & understandable) that I didn't have time to post on Twitter how amazing the talk is not to loose a second of attention.

And giving away books to help people with getting on Elixir train was a nice touch.

Incredible talk packed with demos and both theoretical and practical information. Great delivery, well rehearsed and timed. This talk should be a case study on well executed tech talks. Giving away books and e-books to people who asked questions is a really nice touch.

Utterly professional.

Every time after your talks I need a day or two to digest and process all the info you presented... Every damn time.
Thank you for that!
