Although there're templates (https://en.wikipedia.org/wiki/Template:Hidden_title) to do it, but pages using it (https://en.wikipedia.org/wiki/Wikipedia:Article_wizard) still have "From Wikipedia, the free encyclopedia" shown.
Also the title can be hidden by CSS (https://en.wikipedia.org/wiki/Wikipedia:FAQ/Main_Page#How_do_you_remove_the_title_of_the_Main_Page?) but this means we need to edit common.css each time we want to hide the title of a page.
