  This is what legislators and politicians have done for centuries.
  There are criminal, civil, business... categories, parts, articles,

  The flat space may be the logical result from your initial ambition: a
  "positions" database. You don't want to write laws, you want to
  influence parliamentaries.

  The flat space also has some flaws: who set the tags and at what
  moment? how many tags and elements under a tag? what logic to organise
  the tags? how to avoid a very large flat space? how to present a
  question when it is present under different tags? how to then organise
  delegation conflicts?

  In fact organisation is important for one reason: delegations.

  Plus I believe a good one could be mapped to other standard ways to
  use internet: mailingList/newsgroup/forum...

  It will be difficult to ensure. Depends on who set the tag(s) I guess.

  In a large flat space, navigational aids will be necessary.
