“In their blog, the Zenbe folks have explained that this keeps Flows more tidy. It might, but one size doesn’t fit all. To be a true collaboration tool, Shareflow should at least give the originator of a comment the choice of allowing others to edit the comment, even if that isn’t the default behavior.”

That’s my beef with a lot of things. Case in point the threaded feature of GMail, which can’t be turned off to revert to being ordered simply by date received. It’s wonderful that you have a default behavior that the majority of the users like, but give some options, especially when it doesn’t take a huge amount of effor to accomodate the customizations.
