What I found those information in Reddit is that they are current with the information than SO. The results from SO are dated back to '08 to '17 and they are often outdated. If the thread is locked in Reddit, they can create a new post and add the link to locked thread in the comment and seeking for more solutions, they are often keep it up. Compared to SO which will locked it up for being "dupe".

This is particular annoying when it comes to CLI tools. Often the search top result will show outdated SO post that the command arguements are depreciated, it took me hours to find this out after couldn't figure out why the command are not working. If I search the problem with site:reddit.com, the answer are usually relevant and current with a working command.

SO's overaggressive moderation are preventing the new information from being relevant. That's why people flocks to GitHub, Discord, Reddit, and Steam forums because they don't share the SO moderation philosophy.

When you hear someone say something like that, what they mean is get involved with the related community on Reddit, or Discord, or a forum.

SO had various communities and they were quite helpful for the time, and if you hung around for a bit you got quite a good group.

Most of that has (sadly, imo) migrated to Discord.
