'tip of the day' macro

Its pretty neat having a 'tip of the day' pop up when you're using an app. It'd be really cool to use Confluence to write these, as child pages inside a TipOfTheDay page.

Then all we'd need is a simple little macro, not unlike the blog post macro - but which just renders a random child page.

Then we'd be able to submit tips of the day and then include them inside a home page every time someone go's to the home page.

Neat eh? It'd be cool for us all to adopt this on all our projects / products.
