Some of you have written privately to complain about some of the ads that show up on this site. Believe me, we are not always thrilled with them ourselves. However, we have a contract with an online ad company and the revenue we receive from these ads is a major factor in helping us keep this site operating. Please be assured that we do not select the ads. In fact, the ads showing up on your computer are probably not the same ads that show up on mine. Web marketing is so sophisticated now that highly specific targeting is possible. For example, a few weeks ago I inquired about purchasing a particular product. Now, every time I go on the web some banner ad is hawking that product at me.
UD does not necessarily endorse the products advertised in the banner, and we appreciate your bearing with a little inconvenience so that we can continue to bring this site to you. Thank you.
