In our days, seems that Squeak has evolved to several different audiences, with an important focus on web development. And, being a Smalltalk, is very good for such target, as to almost any sort of software development.
Even though, part of the original spirit of Squeak was to be a tool to help childrens learn anything on the school. A tool to help teachers to develop new ways of teach, making possible new ways of learn.
Such spirit is alive on our days on Squeakland, were several of the original people from Squeak team continue working.
The Squeakland site is plenty of fresh resources to such sort of Squeak use. Enjoy it!
