Definitely true. The landing-page thing is the IT equivalent of "is it plugged in?" If you can't get anybody to give you an email address, then you'll never get them to give you money. But just because people are interested doesn't mean they'll pay.
In both these cases, I would have taken them as signs that I had some unarticulated, untested hypothesis in my head, and that I'd have to do user interviews to figure out what the issue was. People are weird, and business is extra-weird. Debugging a value chain is often way harder than debugging software.
