I think it depends on the specific source, and content... This isn't like the typical advertorial tech blog posts that a lot of us see. Auth0 is the one that really sticks out to me on that regard, though far from the only one.

So long as the blogs are well written, informative, and have some technical depth; even if from a single-source they have value. I could see similar blogs from any number of technical resources. MS bloggers have similar quality and often show up here regularly. FB as well. It's a matter of quality, and the voting model tends to bear that out pretty well.

I don't know... You might be right that the voting part can take care of this. What I fear though is that the community will get used to this idea that there is no point in submitting anything that is outside of the mainstream, because the mainstream is already using HN, and any fringe topic will be drowned by the other voters.
