Is it?
When I worked in networking, and later web dev work I found Reddit to be a TERRIBLE place for Q & A type situations.
Answers on Reddit are often skewed by truthy answers from people with limited perspective in the industry who are surprisingly sort of militant about a given topic.
For example the networking topics often were “small shop” focused and users unaware of very common enterprise level practices, and when they saw someone mention it they would react really poorly. The result was advice tailored to small shops that have limited staff, so you got ideas that “work” but would perform poorly at scale (at best) and at times could present security risks, miss opportunities where more performance was needed, better solutions were available with a sizable staff and planning. They weren’t wrong, but the answers were skewed.
Subreddits are weird, they might be about a topic but the community often moves that topic/ has a specific pov within that topic… people without those views tend to abandon those subs and those who remain aren’t necessarily “right”. Reddit isn’t stack overflow where being correct is at least on the surface valued where we can run code and see if it works. Top answer on Reddit could be wrong and anyone taking issue with it may simply not answer. Heck there are whole subreddits dedicated to wallowing in misinformation…
Now I don’t know if Q&A is the start and end of LLM training (not my area of expertise at all, I am open to the possibility that what I’m talking about isn’t a problem at all) but Reddit as a source makes me wonder what the results would be.
