I really use WordPress as a CMS and often review and edit older articles. When I do this I sometimes republish with today's date. However, that makes it appear that they are new, and this may confuse returning readers.
Is there a way to list posts in order of last edited instead?
e.g. the "top" article on my homepage right now was Published June 18th, 2012; edited September 20th, 2012. I made it a sticky to force it to the homepage. But if this was automated that would be pretty cool. I think.
