Starrs!! I'm feeling you man, let me pull together my thoughts and I'll give you a proper reply..
As Shirky shows : flicr pics on a certain subject is mostly contributed by a core group (06:51). I bet in a DD system participation would look similar, with the persons that have an interest in a particular issue being more active in that sector - In my case I would be more occupied with matters relating to the building industry, than health, for instance, simply because I know that is not my expertise and I don't want anything to do with that.
All men(women) are not worth one vote. All men however do have a right to effect our society through the Laviathan. Not all men would be interested to be intensely involved with decision making, while persons with real interest and knowledge in an issue, need a voice strong enough to be heard against predatory interests.
The time is past where we see one man needs one vote every 4-5 years. In (what you call a constitutional direct geniocratic democracy - have you written more on this... sources? ... would love to see more thinking on this!) where voting would be taking place constantly - daily mini referendums, any person with recognized knowledge on a particular subject, should have a vote that is weighted to balance against persons that is not versed in that subject (But they will still be able to participate)
This could draw the "wisdom of the crowd" rather than subvert to the "tiranny of the mob".
Thanx for the thread, even though it might be a quiet one
