To do:
Have a way to limit the number of links that show up. (based on webmaster's input)
Make the links show up in random order due to that fact.

That is one I have been thinking about and plan to implement in the very near future. As far as the random order, I didn't think of that but I like it very much. I will also be looking into categorizing everything so people can choose what categories they want to display or they can display multiple categories.

I was also considering paying bitcoin related websites a small fee to post it on their site. But I would have to figure out a revenue stream for that based on their traffic. I am pretty new to java script but I know a few other languages so it's not a horrible transition.

That is a great suggestion! Please keep them coming.
