Stef, Thanks for your input/reassurance. Vassili Bykov has a nice blog enty (Nov 2005) on announcements, and after skimming that, I have a much better sense (hopefully a correct one<g>) for announcements. Given that #trigger:with: can carry arbitrary information, it seems that announcements are a smaller change relative to events than events were to depencies of the MVC era - I'm still trying to forget about the latter. Thanks!

Hello all,
I know there has been a fair amount of discussion of event mechanisms; I have not been able to follow all of it, and have probably forgotten most of what I did manage to absorb. That said, I _think_ I am fairly flexible as long as there is some way to trigger events and get messages sent to interested parties.
Dolphin calls uses selectors such as #trigger: and #trigger:with:. Pharo has methods called #triggerEvent:, etc. Is that done for a specific reason? Am I walking into any traps by forwarding them to #trigger: and friends? I do not think so. Announcement is nice because you manipulate objects.
