Apparently message passing and queuing is a big part of a web application

used message passing/queueing in a web application. I recently read an
article about IBM Websphere somewhere talking about how great it was and
that it had these technologies. What does anyone use these things for?
Message queueing/passing comes into play larger and distributed web apps (multi-tier, multi-platform), often when connecting them to things like mainframes. You would implement that extra layer in your app when you ABSOLUTELY CANNOT lose a transaction, anywhere along the pipeline. Think accounting, customer billing, government reporting, inventory management.
Websphere has it in their J2EE stack, JBoss has it too, and there other companies which make their living making MQ middleware (http://www.swiftmq.com/)
Another issue: And why is it so much easier to find Zope developers to ask
questions of than Websphere developers if Websphere is so popular?
Websphere is used mostly in large organizations where they have internal developers. When they have questions they ask internally, or call their contacts at IBM. When things don't work, they use their support contract with IBM to get expert help. I'd venture that they're much less likely to be sitting out on the internet watching mailing lists and IRC since that's not their first line of support as it is for people with Zope.
That said, http://www.websphere.org/ :)
