Of all places to host your community in, why Discord? Discord is not indexed by search engines. If you wrote a long, thought-provoking piece there (I've seen many people do it), it practically lost forever after the discussion move a few screens forward in a few hours. People from the future can't benefit from what you wrote when they're searching for similar topic in a search engine. The same can be said with Telegram and WhatsApp groups which are popular in certain communities.
