As discourse becomes more and more popular, I increasingly find myself teleported to sone discourse forum via some link. And one of the first things I usually want to know is: Where am I? What is this forum about? And unless the site admins have done an exceptionally good job in formulating the essence of their site in a single sentence in site description (which is shown on the About page), it’s often not that easy to really understand what that forum is about.
How about adding a long site description field to the site settings and show it on the About page?
