We are going through the same approach with our current beta customers (and will be making our demos available to a wide audience in the future too) and I can attest to the validity of this approach. We make it very clear to our customers that this is a demo and their changes will go away if they refresh the page. We don't have pop-ups integrated since we collect emails on another page. I think event tracking should be sufficient but we'll have to see what the data says in a little while.
We actually also use these semi-live demos instead of mock-ups (since we'll be implementing the same pages afterward anyway) since only one of us is proficient with Photoshop but everyone is comfortable with Bootstrap. It serves as a testing ground for various approaches for JS code too.
Dad tried to teach me how pointers worked when I was 6. When that didn't really stick, he tried flow diagrams. That seemed more fun than Barbies but I didn't come back to computers until 7 years later when we finally got one at home. I loved playing around with pictures and Word Art in MS Word so dad got me a "for dummies" book of sorts. It went downhill from there. :P
So sad. I distinctly remember how my sis and I (female) got a pair of generic brand transformers as a present back when I was 8. Dad was inspired after we watched Voltron every Saturday! Of course, my sister (being slightly girlier than me at that age) promptly used nail polish to paint its ugly-grey "shoes" because we needed to distinguish "ours" but still, what fun! It turned into a fighter plane and back and we'd spend hours playing with it.
... I mean, no, girls don't buy toys. Maybe if they didn't explicitly make it boring and discouraging for girls then they would?
When you have 3 kids to take care of and have no background in finance/accounting/etc. do you really want to start getting into THOSE details too? Why would you doubt your husband, the man who's supposed to take care of you until the death do you part?
Netflix makes it pretty obvious that you're signing up for a monthly subscription. It is also a pretty well-known fact about their business model so it's much harder to be "duped" into it.
That may be true for some definition of informed but I'm inclined to think that there are many informed people using gmail (and other Google services) and this fact leads away from your assumption.
But it's perfectly reasonable to think that Google might drop a service like "Sites" if they aren't able to monetize it, or if they think that it competes with another of their services. It isn't currently reasonable to think that of gmail.
