In general, I'd say it's always wise to follow individual
people whose knowledge and expertise you know and trust rather than browse a platform. HN is one of the few exceptions I make, because I'm very likely to find quality people/content that I just wouldn't have otherwise. So yeah, blogs are great if you choose wisely.
Btw this was the cool thing about blogrolls -- if I trust someone's opinion, I'll likely trust the people they trust. You can replace "trust" with "be interested in".
