At the moment there is zero advertising available to see on our site. That makes this feature pretty easy to implement :-)
In the future, we'll add a link here so if you want to look at some ads you can go look at them. Otherwise you can also search for them using the Search field. Our site will not put advertising on your screen unless you make that choice. That's the way the World Wide Web used to be.
A system where the user can "PULL" ads into their account is where we are headed. Nearly every website on Earth "PUSHES" advertising into your face, whether you want it or not. At least Twitter lets you block advertisers.
