PickAFig.com aims to be the digg for Catholic matters.
Best of luck to them. These clones often run into trouble and go extinct. Perhaps this is because their focus is too narrow or because their target audience is already using their model and sees no need for a duplicate.

In less than a week of operation, PickAFig has picked up about 80 registered users. A good start, but not enough.
