Most people who make things online are scattered across half a dozen platforms that do not link to each other. The place you can actually point at is one line in a bio — and that line only fits one address.
The tools that fill that gap mostly produce pages that look identical to each other. You can tell at a glance which builder made them, which is a strange thing to accept for the one page that is meant to represent you.
So the thing we care most about is that two Formza Bio pages can look nothing alike, while both still looking like someone chose how they turned out.
