I should have given an example above -- here's my 'mobleo' tag that has the URLs I want to show up when I visit the http://mobile.mobleo.net/ website on my phone, which I mainly get from this thread of yours:

http://del.icio.us/rivviepop/mobleo

You can see how I then get to add my own unique categories which would maybe be in addition to yours, or replace them because I have a different personal organization system (not that I do, my account looks like a shotgun blast of randomness, heh).
