Link List for Internet Demographics
Marcus Zillman has started a link list for Internet demographics. So all those of you e-mailing me asking about Internet demographic angels-and-pinheads, start here. This site features an alphabetical list of Internet demographic resources, unfortunately without any annotation (MAR-cus!). In addition to the demographic portal Marcus has also put together a listing for hoaxes etc. , a listing for Internet experts , and a cool listing for information futures markets.
