Everyone removed their blogroll. That is what happened. Someone gave Automattic (WordPress foundation that could receive "donations" from advertising platforms) the idea that making blogs mostly discoverable via paid advertising was a good idea. Automattic removed the blogroll by default, and then most of the blogs removed, and then most of the blogs vanished. Blogs were discovered via the huge list of other blogs. There were so many incredible blogs. One could then check all their linked blogroll blogs because birds of a feather flocked together...

Automatic became an NGO. A big advertising seller paid the NGO lots of money. The NGO removed blogrolls so that blogs were discoverable by paid advertising instead of word of mouth. Countless blogs also removed their blogrolls, and blogging declined.

That is one more thing that Google has done to destroy the web that gave birth to it. That happened around 2012.

Also, old blogs were like having a subject matter expert as your personal mentor via correspondence. Those new blogs would have been called content farms in the days of the blogroll. Search back then was based on keywords and boolean. You could type "NOT youtube" and no youtube would fill your results. The top blogs are content farms by the old standards.

Google removed the ability to use boolean search to get exactly what you want based on text content, and then they removed the blogrolls via bankrolling the WordPress developers. Now the top content farmers get top billing on every search engine, which requires marketing spend, the blogrolls are niche structures, and you cannot boolean your way to a real set of search results.

Blog search was good, Technorati was good, google reader was good.

But I agree, if it doesn't have a blogroll it is safe to ignore the blog. It might even be considered the single identifier that separates the blogs from the spam.
