I put my email down to spy on you:)
My personal feeling is that (A) you're totally right that we need better _personal_ organization systems, but (B) the bottom layer (tagging, schemaing, relationships) should not involve fuzzy processes but should be totally understandable by the average user.
I know (B) is a weird opinion though so I look forward to seeing how far you can get with (A) plus machine learning & whatever other tricks you guys plan:)
