If you are scaling up, profitable (or speculated to be very profitable in the future), and eventually get big enough to do an IPO, then yeah why not? Booking.com a CRUD website making hotel reservations, and called a tech company.

What is missing however in the picture of "someone building a site" is the other points mentioned in the essay: network effects, building a platform and forming an ecosystem around you. Everyone can do it, but not everyone succeeds. This is why there is such a big rush within tech startups to be the first in a space.
