Long thread...sorry for the delay in replying.

Just like Zope.org, content can be anywhere.  But giving people a
"me-centric" view of their content is powerful.

I don't buy the argument that putting stuff close to people breaks
URLs.  Take a look on the web at all the ~username URLs you see out
there.  Moreover, deleting a member doesn't delete their content, just
like deleting someone on a Linux system doesn't delete all their files.

Regarding the idea of folders based on categories, this is precisely
what Topics are to do, with the advantage that the same item can appear
in *many* places.  A Topic is like a folder where most of the items come
from a catalog lookup.

Note, thought, that the items aren't _really_ in the folder.  When you
click to visit the item, it goes to the real URL.  Perhaps that's not
what you want.

Hmm, are you saying you can't create a Portal Folder, then create stuff
in there?

Yep, that's an issue.

Hopefully Topics will help this.  I'll check on the ETA for Topics.
