Wishlistr is more a Web 2.0 interface than a web 2.0 applications, though it has nice AJAX usage in few common places. Wishlistr helps make a webpage with the links to out wishes. Just like Amazon wishlist but you can choose from few very nice designs to show up your wishes. Not that great still pretty sweet ;) .

Requirements :
An internet connection and a modern web browser, such as Firefox, Safari, Opera or Camino. Internet Explorer 6 will also work. Wishlistr also works best if you have JavaScript support turned on in your browser, but it’s not a requirement. Wishlistr does not support Internet Explorer 5.x and below.
