It seems Bertelsmann are about to invest in the European search engine Quaero.
AFAIK Quaero remains just a project in computer labs at the moment but I spy a few fundamental difficulties with their url, http://www.thomson.net/EN/Home/Quaero/. Firstly it is not exactly obvious. Secondly you need a thompson.net username and password to get at it. Thirdly someone already owns the Quaero top level domain, http://www.quaero.com/, a marketing consultancy which describes itself as a "marketing and technology services company that provides unparalleled value to firms looking to improve the effectiveness of their comprehensive marketing efforts and marketing technology investments."
