All, i have been utterly delighted by this conversation. What i can't help but think about, however, is that with the internet we have a different sort of opportunity. Let me try to describe it. - What is missing in most mathematical presentations is a view into the often very human and very messy process of getting to the presentation. What young mathematicians need -- in my view -- is a view of mathematicians doing mathematics. They need to see very top-down orientations rubbing elbows with very bottoms-up orientations. They need to see highly inventive, unifying viewpoints come up against skeptical viewpoints armed with vast arrays of counter-examples. They need to see people desperately trying to organize while others are desperately trying to de-construct. This is where the life of mathematics is. This is how people bring mathematics to life. - With the internet we have the opportunity to record not just the final artifact, tractate or wiki, but the process. Ever since Andre Joyal mentioned a 2nd life for Bourbaki i can't stop thinking about a Bourbaki colloquium run in Second Life <http://secondlife.com/> -- so that whatever the outcome of a given process is in terms of artifact, people can go back and look at the process, itself. They can see how people argued and counter-argued. There is getting to be a precendent for this, from Harvard<http://www.joystiq.com/2006/09/12/harvard-class-invades-second-life/>to Intel <http://softwarecommunity.intel.com/articles/eng/1283.htm>, to run serious technical conversation in Second Life. Perhaps this idea is too far out, but i would urge those who seriously consider a second life for Bourbaki to remember to record the living part as well as the outcome. After all, looking over the last many emails to categories so much of it is an attempt to recover process -- how things got to be where they are.

Do we imagine this new Bourbaki as just systematizing and presenting what we know already, or struggling to create brand new mathematics?
This is an important question. We need to have a clear view of the goal of such an enterprise. From my point of view, the goal should be "educational": to help students and researchers to learn mathematics and cross the boundary between fields. Mathematics is vast, and every mathematician is a permanent student. The traditional way to learn is to read the litterature and to discuss with a master. I was told that Grothendieck had learned algebraic geometry by discussing with Serre. But few peoples have this chance. Obviously, Internet is opening new avenues for learning. Many peoples (and myself) have learned a lot by reading your bulletin "This Week's Finds in Mathematical Physics". You have a real talent to explain a subject by exposing the heuristic! A discussion forum like the "Categories list" is also very helpful. Wikipedia is a useful place to gather informations about a subject. But the Bourbaki Tractate was offering something more: a unified presentation of mathematics, including the proofs.
The Bourbaki Tractate was the result of a sustained collaboration of many generations of mathematicians from different fields. Conflicts are inevitable and mathematics evolve quickly. A unified, final presentation seems impossible.
