I would like to share an interesting and quite helpful side of search engines and their personalised searches. Google Flu Trends http://www.google.org/flutrends/ch/#CH helps you to follow the ‘evolution’ of a flu in your region. It tracks search entries of that topic and combines it with the time of the entry and Google maps. Of course, a too paranoid view on this isn’t constructive, but I think that it is important to mention both negative and positive aspects of personalisation in online searching.
