I know why it is a weak hash, I was not implying it was strong but it
is still useful for many applications that still rely on it, for some
protocols that use mixed hashes [md5/sha, ...]. Not to mention that a
use coupled with salting for the master.passwd database isn't weak in
my opinion.

haha, that was a good one :)
I *really* hoped you would paste a collision and prove me wrong ...
And yeah I *do* know it is possible but I was trying to make sure it
wasn't just "yet another crypto expert" talking ...

read 1-, there is a difference between pro-active advocacy of new
protocols to deprecate old ones, and removal of a key feature upon
which many tools and protocols are still relying.
