Someone on another list asked an interesting question:

      Why did OTR succeed in IM systems, where OpenPGP and x.509 did not?

(The reason this is interesting (to me?) is that there are not so many 
instances in our field where there are open design competitions at this 
level.  The results of such a competition can be illuminating as to what 
matters and what does not.  E.g., OpenPGP v. S/MIME and SSH v. secure 
telnet are two such competitions.)
