Random Post button..?

Hi there, i was searching for the same thing, so after a small search i found some code snippets and decided to do it without a plugin.
The great side of this story is that i’ve implemented it with a CSS button that has “explore” on it.
I wrote a complete tutorial about it and you can read it Here
You can do it with that simple snippet and also add a cool css button instead of a simple text link. Cheers.
