How to Spread the PrintFu Gospel ? Any Ideas?

So I think PrintFu is a great little idea. People get a great product for a great price. I get a couple dollars, the Printshop Makes some money. Everyone is Happy. What a killer thing. No one is getting screwed.

Now I want to figure out how to spread the word about PrintFu. I want more and more and more people to Love it like, the current people that do. The PDFURL hack, has really helped spread the word to the geeks, and thats about it. The "make-a-buck" help paying people for referers. in an insanely simply way. But know I want to know what the next thing is.

Will you help?

What should PrintFu do, what is going to be the Next Big PrintFu Thing!

Again, everyone thanks for the support.
