I'm forced to agree. This type of free-flowing organization offers a much wider ability in the area of usage. I'd like to suggest however that if it were considered, so then might be, a core or initial tagset from which branches might grow. Making them vanilla enough to be useful and unconstrictive, both giving some internal engine the ability to make relevant high-end references to any user created tag. And perhaps even a method for users to update or grow the coreset, with obvious limitations.
This might help handle the initial potential for it growing into chaos and also give any "transition software" a leg up.

an 8 hour collision isn't exactly death. it's totally dependant on the application's use of MD5. for instance, PHP uses MD5 inherently as a form of session identification. and it's more likely to expire and be re-issued over the course of 8 hours depending on how carefully implemented it is. so, until we're talking minutes, and not hours to collide completely, the issue is very much still open. i agree its grave is certainly dug, but until they reconcile both of these methods and develop a unified method leveraging the advantages of both, MD5 can still be carefully and safely implemented. theres no reason to believe that process of reconciliation will be instant. as a careful developer though, i never used MD5 for anything. early on, to me, it was somewhat obvious that this would eventually occur.

RE: MD5 collision method published

Herein a US Marine tells a slightly different tale about how our good buddy Saddam was captured. Whats striking to me is how much more likely it is, that this is what happened.

Take into account the other version of this instance had you believing that, what the US described as the most egotistical "dictator" of a state-nation, was found alone, unguard in a hole. And that he was taken prisoner no-harm-no-foul, in the middle of a large campaign that spanned the entire region (of which he was the leader).

What makes sense?
