Otto published a snippet of code that, when added to your functions.php file functionality plugin, will give you a URL you can use to always bring up a new random post from your site.
I have mixed feelings about code snippets, which is why I tend not to link to them very often. In this case though I made an exception because I’ve actually implemented the snippet on WPCandy. Visit wpcandy.com/random for a random post. I hope it’s a good one!
Do you use a cache plugin? I always get the same post displayed, even after refreshing and in another browser…
His link seems to work okay for me in Chrome. That’s the point of the 307, to prevent the browser cache from, you know, caching.
