There are several advantages: 1) You don't reveal the social connections by signing keys. If you want to validate a key by its signatures and see a signature of an unknown key then there is (IMHO) no reason why you should know who has certified this key. This information can easily be abused. The perfect web of trust would be the perfect source of information which should be considered private (who knows whom). This problem is hardly reduced by the fact that there are signatures (from key signing parties) from people without real social or commercial contact. 2) For people in countries where authorities' rights and actions are not as easily ruled unconstitutional like in Germany (or not at all) it is useful if not only the content of their communication is hidden but also the identity of the communication partners (even of those in free countries). This is, of course, more complex than hashing a key ID, thus I am not sure how important this feature would be (as you have to hide the partner's email address or the connection to the identity and these email addresses have both to be kept secret (because you can easily hash all "publicly available" addresses) and to be complex enough not to be guessed; this may result in greatnesses like sqq8ctpmbf81yucw8nzwb...@hauke-laging.de). In general it is useful for a web of trust to have long living keys. Email addresses are more easily changed than keys. 3) You prevent spammers from using keyservers as a source. Yes, I am aware that certain people on this list don't accept this as an argument (for different reasons). The most important point for this question is probably that the infrastructure has to be safe BEFORE it gets so big that it becomes interesting for spammers. > Another reason why we all love Germany now. ;) According to a new study it has the best worldwide image of all relevant countries worldwide.
