Totally know what you mean! When I was researching the rankings, I found so many lists that are clearly made by people who are literally just googling other lists and copy/pasting them.
The results so far are pretty cool and, in my opinion, should be a signal that it is TOTALLY possible for individuals writing great technical content to stand out for a specific technology.
One thing I noticed is that if you write a blog about tech topics, you will suddenly be competing with the shallow blogs of vendors in your niche.
They have people and resources to waste in content marketing, you don't and it's a struggle to be discovered on google by other engineers.
A good aggregator that optimize for "discovery" would be awesome!
