Wishlistr's website describes it fairly well:
Wishlistr is an easy to use web-based application that will help you collect, organize and keep track of the things you want. It also lets you share those things with friends and family.As with most of my favorite apps, this one is free. And it's simple, non-intrusive design makes it idyllic for keeping your list of Christmas wishes. For those who are more tech-savvy: Wishlistr even includes an RSS feed, which could be helpful if you want to subscribe to someone's list.
Try out Wishlistr this Christmas and avoid getting another tie or calendar this year.
