Good cookies and bad cookies (Score 2, Informative)

With deleting all cookies many people are doing themselves a big disfavour, because session IDs then mostly get embeded into URLs instead (= you loose the logging feature, while sites could still track you).

What's always left out in these discussions is the differentiation between good cookies and tracking cookies (especially long-lasting session ids). See also cookies(5). Lack of user education and bayesian cookie filters in browsers IMO.
