Posting Class State via Notifier

[lvb]

I've been using notifiers lately to post the state of a class throughout the application. This has become a very easy and convenient way to create some basic user interfaces and share class data asynchronously.

Just wondering if anyone else uses this technique (or User Events)? Any pitfalls?

Used to do so back in 2006. Worked, but didn't scale well beyond two modules in one app, for various reasons. Learned a lot since then about scaling up dataflow. Generally dropped the technique entirely these days -- avoiding anything that even remotely smacks of sharing state data anywhere in strong favor of message passing systems that scale much better in my experience.

But the notifiers are a reasonable starting point for exploration.
