I think the reason behind any act of moderation comes under the domain of the meta discussion of the website. Thus, the reasons behind the suspensions should also be open to discussion on the meta website. I, by no means, intend to say that the decisions regarding the suspensions should be made directly based on such discussions or by popular vote. That right is rightly reserved by the expert moderators for the good. But since the suspensions are decided based on the public behavior of the user and the policy of the SE is also public, I see no harm in discussing the precise reasons behind a particular suspension. And besides, dogmatically not disclosing the information about any suspension (for example, Ron Maimon's to be explicit) seems quite silly if not anti-democratic. I know that the information can be accessed by personally emailing the moderators but I don't see why discussing it on the meta website is not encouraged.
