There's a lot of good troubleshooting and tech info on there, though. I've run into multiple tech issues over the years that aren't documented in bug reports, change logs, etc., but some random person on Reddit will have a post where they investigated the cause and found a solution.

For software, if it already has the cloned source then it can just look at how the thing works directly and answer you completely. I should think they'd already be cloning all FOSS repos and that it'll eventually just do that.

And quite often a thread isn't just a problem and a solution but the set of steps to get to the destination. Even if it's not the exact same issue the process is useful.
