StackExchange is my goto for Squeak questions. The mailing lists cannot compare.
Also, the last several years have been very tough economically. Just scratching to survive, no time to code.
Currently coding an application in Seaside.
For wider use, you need mindshare, that means the CLI centric Linux crowd and incorporate the language/cogvm into everyday Linux development models .
However, the GUI is essential for other dev types; I am not knocking the GUI, just recognizing need for different users.
Squeak is a blast, though. It is the first (besides SQL) non-algol language I have used and I am never looking back.
I hope, as time frees up, to work on the REPL and decoupling the Squeak from Morphic/MVC . Would love to create an X Desktop with it.
Good luck.
