I think that's the point. They are not in 100 places, they are in one. If you want support about Jellyfin, you go to Jellyfin. It was always kind of stupid with Reddit.
I need support with Jellyfin, so I go to Google, write my query, add Reddit at the end, go to result that may or may not be related, try to discover the difference between the 3 or 4 different but related subreddits to find out which one is the official. Discover that none of them is. Find another sub about cutting cable. There's a vague answer that's similar to your issue but not exactly. Maybe try asking them directly on Twitter.
Now you just go to jellyfin.org and the forum is right there, search there for your issue or write your answer. All in one single official place that is looked at and maintained by the very same team. It's just better overall
