I only realized very recently what makes me uneasy with web advertising. (This week from a HN comment)<p>If you see a billboard in the street or an ad in paper journal, you are exposed to the brand name for a few seconds and that&#x27;s it.<p>If you are exposed to a web ad, you are exposed to the brand name for a few seconds AND your actions, the fact you have visited the page, from which IP at which time of the day, with which browser is recorded in a database for later use (and is certainly going to be sold or replicated by multiple entities).<p>So it is not so much the advertising part that his annoying but rather the &quot;tracking&quot;. The fact that advertising network (or social buttons) are pervasive through many sites makes the matter worse.<p>The biggest lie is to still call that &quot;advertising&quot;, this has nothing to do with old school advertising.
