"Baidu knows" now lets users publish documents online,
which others can download. The documents can be in one
of the common formats - .doc, .txt, .pdf... Baidu expects
users to upload theses, articles, published papers, test
banks, courseware and the like. About five thousand
documents have been uploaded already. The system
works with a points system, with those who upload
earning points which can be redeemed toward downloads.
