Hey Ariel, I like the idea that you gave use the option to annotate the document to give Feedback. The tool was easy for me to set up and not complicated to use.
However, I think this section of your explanations leads a little to confusion. Maybe it's just me, but I wasn't sure which link to click to annotate your Techshowcase. I wish, you would add this: If you'd like to try annotating my Techshowcase, follow the steps above and then you're most welcome....
It's just a minor detail though, I really enjoyed the clarity of your explanations.
