Great presentation! Of interest to people who want to use a CMS and also to those interested to know how the platform works. Mark fielded an enormous amount of questions from the audience and with great expertise.
It was very nice seeing someone talk where you could tell he had extensive knowledge on the subject. There was a decent balance of showcasing MODX and the technical aspects of it, there could've been a little bit more weight on the technical side.
My feedback would mostly be on trying to keep a more upbeat voice, this is to keep the audience engaged and making the talk a bit more fluid.
Overall, good talk!
I wouldn't want to have missed this talk about an interesting CMS. It is clear that Mark knows all the ins and outs of ModX.
Mark is not a very extravert speaker, but that's not what I expect on talks like these.
