Okay I'll elaborate, it's better for community building and answering questions for nascent companies or organizations. A lot of the time there's a big disconnect between a community and how a product is intended to be used.

I built a paper trading app for stocks and options and Discord was the primary place where the users talked. The subreddit was almost completely empty, nobody responded to tweets, the Instagram was thriving but there was no sense of community because you couldn't tell if anyone commenting actually used the product or a meme just showed up in their feed.

Did I have to repeat myself a bunch? Yes, but that's fine, especially because the answer sometimes changed (rapidly), like "No we don't support multiple trading accounts per user" > "Yeah I implemented that last week, it's in the release notes, to add a second account..."

For a mature product that's not changing as much and more or less has all its features built out, it makes sense to branch out into more structured forums that are easily searchable, especially as you progress through different versions and users are looking for answers to past versions.
