No worries :) Your are right, a Product Manager is still different from a Project Manager, but the lines can be blurry. I was a Product Manager as well, at one point, but I felt that was even more difficult than being a Project Manager. It felt like I had all the same responsibilities as a Project Manager, but on top of everything I was supposed to be some sort Steve Jobs-esque visionary. Which I am not, when it's not my own product, as it turns out, haha.
