That is an interesting point.
Another thing I find strange and frustrating is that google is showing the list of topics from my “uncategorized” list of topics, and not the topics that I show on the home page (the /news topics)… which are the personally chosen and highlighted news posts for the site…
In theory there is a sticky topic already - the “welcome to site” post that Discourse shows for all new, and unregistered visitors, which describes the site etc…
But for some reason Google ignores that post.
Yes - as a temporary fix, I will try a sticky post that might work as a google “site description” lacking our real site description.
Its funny - you can get a search result that shows the new longer meta description for my site, but I can’t get it - even in incognito mode, even when I try different web browsers…
