An advantage over what? Reading an SO page "scrapes" the whole page with your eyeballs.
Anyway, I didn't say anything about which is preferable to use, I merely commented on where the information comes from, so your response is non sequitur. If sources like SO go away, it will affect the quality of LLM responses. "the same question from countless other parts of the internet" is a figment of your imagination when it comes to the kind of content SO accumulated. I've been in this industry for a very long time (my name appears in RFC #57) and I know what it was like to try to get answers to technical questions before SO showed up.
