Do you see that page as a good or bad example?

Well, I'd seen the term 'Continuous Linear System' somewhere and came to this page, where it starts out as:

Consider the continuous linear time-variant system

<equations!>

so, bad.

It's a math topic. Expect equations.

The problem is not that it has equations, it's that, unless you already understand the topic to some level of mastery, you can't even understand the page...ergo it's not a useful resource.
