I tried to read https://joinmastodon.org just now, and got held up by the columnar layout. Best to avoid columns. (Also, side-scrolling is the worst!)
Not sure where to direct this, maybe @Gargron ?
(screenshot of joinmastodon.org with heading "What our users are saying" followed by six columns of text, all truncated to about 3 characters each making it impossible to read)
