Matchlogic (owned by excite and went down with them) had a pretty cool system to keep track of I-forget-how-many millions of users. The trouble was that it, at least at the time, actually wasn't cheap to run. It took them a relative large amount of effort for relatively little gain (in clicks/acquisitions/signups/etc). Around the same time I recall that DoubleClick were winding *down* their system doing it. The story I heard was that it did work (increased the results by something measurable) but their technology cost to do it made it not worth it in the end. Of course it's some time ago and with Moore's law and substantially cheaper hardware and storage costs, who knows... Hmn, maybe I should go back and work in that industry again. :-) - ask Years ago when I worked in that industry, there were a few companies doing it.
