From: Tom Gray [mailto:[log in to unmask]] This is an important issue because the potential value of the network seems to depend on its ability to identify the preferences, location, activity, and other information about users. Only in this way can the network adapt to the user and offer services beyond the rudimentary. Most people according to the research do not object to the gathering of this type of pervasive information. ======================================================= That is what Madison Ave et al. (good old al.) have been doing for a couple of generations at least, with the general consuming public. You have described a logical extension of that behaviour into a new, available area. BTW, the word CONSUME means to waste and destroy, which is, of course, what our consumer culture is emminently good at. A former name for tuberculosis is CONSUMPTION. We have a self-inflicted tuberculer social infection. Cheers, Peter
