I think providing a way to browse data hierarchically through
user-assigned tags is the first item of business. This will look like a
normal folder tree view.

We can also provide tag completion not just at the time of tag
assignment but also at the time of recalling items using tags. So, I can
start typing a tag


and PB would complete

       irefox (39)
       riend (48)

then I type i and hit tab


now when I type comma and space, I get other tags of things tagged as

    firefox, |
                extension (18)
                flaws (6)
                hacks (13)
                javascript (2)
