The most active Smalltalk inspired community seems to be Pharo.
<a href="https://pharo.org" rel="nofollow">https://pharo.org</a><p>I have avoided calling Pharo "Smalltalk" as it has evolved from the original fork of Squeak and the project is evolving and modifying from its Smalltalk origins.<p>My personal favorite language that has evolved from Smalltalk is Newspeak. <a href="https://newspeaklanguage.org" rel="nofollow">https://newspeaklanguage.org</a><p>The current version runs on top of WASM and can be used in a web browser. Gilad Bracha is going some exciting and interesting things with this language.
