Both the site and the app allow users to add links and put these in categories, even assign colours to these categories. Every category is given its own static address, but static addresses are also provide for the last link you added and your recent links.
As a final touch users can also take part in community challenges to try and create top 10 lists, the idea is that users share their knowledge on the best sites to fill a category.
