I feel like this is where taste comes into play though. If you have good taste, you can find the resources/​people that are worth paying attention to. And similarly, you can ask the right people to point you to the right resources. No?
Relatedly, a working hypothesis of mine is that a big benefit of reading peoples blogs is that you develop an epistemic trust in them, and could then use them for reasons like this. Or maybe use them indirectly: you trust Alice, Alice thinks highly of Bob, Bob thinks Carol is a good resource on operations and recommends a given textbook, so you read a few of Carols posts, pick up the textbook, skim it, and look through the sources that the textbook cites. And it all starts with you having epistemic trust in Alice.
