I want to know this too! When I poked around before, I got the impression that it would be good for writing apps that need sophisticated logic, as the language and the platform is very flexible. I think I came across several Pharo tools for source code analysis and using them also seemed to leverage SmallTalk's flexibility and exploratory capabilities.

I had briefly considered it to use it as a cross-platform desktop RAD platform, but its integration story was pretty weak. Things like connecting to PostgreSQL could be done, but only using an older protocol. Serialization formats like ProtoBuf were not available. The GUI framework was not easy to parse (for me), though there were inklings of work on easy-to use, high-level GUI builders.

I left with an impression that it was for people smarter than me, though I'd still like to learn it!

BTW, I had heard that software for seaport dock management used to be dominated by SmallTalk. Not how things are now.
