Great talk.
A good talk and a good speaker.
An interesting talk and a very good speaker.
Nice talk but I suppose it was too entry level so my rating is 3/5 instead of 4/5 as I'm evaluating it in a "conference optics").
BTW it was good for me because I was there for upcoming PHPDay as I am a backend developer and was nice to follow a topic where I'm not an expert.
