WDA - Contrast Using Message Manager & Application Logs

Question

Hi there, I'm trying to figure out when it is appropriate to use each.  Thus far, it seems that the conclusion that I am coming upon is that the message manager is used for issuing messages at an application user, whereas the application logs should be used to address issues meant for an administrator of the application - basically someone who may be more technical.  How is this assumption?  Can someone provide me with more inside.  I'd love to understand some real life usages.   I've read documentation after documentation, but in short, it would be great to leverage off of some who have actually used this in practice.
Thanks in advance.

As I can see from my point of view the main area of using IWDMessageManager is to indicate to user what is wrong with data he or she is trying to change over UI. For example, to show message "The field XXX must not be empty" or to make another kind of validation of input data on UI level.
The main purpose of logging is to trace possible Java exceptions, to trace debugging information (with severity DEBUG), to log some critical errors for technical staff or administrators. The information from the logs can be unhelpful for end-user.
