If you need a random quotes module there are plenty about.
What I was looking for was something to take a number of daily feeds (javascript) and insert them on a random basis into a specific location within the main content area of the homepage of my site - each time the page is refreshed different content is shown in this position. Randombot does this perfectly. All it takes is one text file containing the different lines of code plus one single insert code in the appropriate place on the page and voila! The page is fresh each time it's viewed.
Couldn't be simpler.
I'm now planning to use Randombot to randomize some affiliate offers in specific pages - it should work the same.
Sometimes it's the simplest solutions that work best!
Well done to the author for identifying the need for something this simple yet flexible.
