If you see an account that looks interesting, follow it!

Don't worry if it seems inactive or blank, it probably just looks that way because you're the first person to follow it from your server. (More info about why this happens at https://fedi.tips/why-does-someones-account-page-look-completely-blank-is-it-really-blank)

Once you follow an account, its posts will start showing up on your server too.

Following accounts is a key part of building connections between servers, and followed accounts' posts become visible to everyone on your server.

Usually I agree with your advice but not in this case. Before I follow a profile that looks blank, I click on "open original page" to see it on their server (which you describe in the article, but don't mention the importance of doing it before you follow). Otherwise, it's easy to follow somedody who happened to make an interesting post but is also racist, anti-trans, or a spammer -- and following them gives them credence.
