Adele Goldberg presents Smalltalk in a TV show called "Beyond 2000" in the 80's. In this presentation you can see the capabilities at that time of Smalltalk. Many of the features are the same that you have today in the modern operative systems.
Since 2004, ClubSmalltalk is a non-profit organization which congregates Smalltalk programmers and enthusiastics. The big idea behind this website is to provide a source of information about Smalltalk in general.
The Smalltalk community has not good sources of information, or they're all over the net, and sometimes it's difficult to find them.
If you want to contribute, you're welcome!
