Pharo is the best representative of Smalltalk today. It is Open Source and free for all to use. It has the most active community (the massive European Smalltalk User Group, or ESUG, is mostly Pharo users). The last release of Pharo had nearly four dozen contributors! The Pharo Project is working unwaveringly to advance the language (with things like the traits model and slots model) and its associated tools. The Pharo IDE has all the good stuff that we value, such as colour syntax highlighting, code completion, code browsing, object inspection, etc. Its powerful new debugger is second to none in the world!
