- Monticello plays the role that CVS does in most open source projects; 
  it's a version control system, aimed at making team development of 
  Squeak source code easier.
- SqueakSource is like sourceforge.net; it provides a place to host 
  collaborative development of projects.  Just as sourceforge.net provides 
  a CVS repository (so that you don't have to know how to host your own), 
  SqueakSource provides a Monticello repository.
- SqueakMap is like freshmeat.net; it provides a central location to 
  announce and to find Squeak packages.  Unlike Monticello and 
  SqueakSource, which are meant to help development, SqueakMap is for 
  final, released code.
- SqueakPeople is like slashdot (or more directly, but more obscurely, 
  like advogato.org); it's a place to discuss Squeak by posting articles 
  or diary entries, and a sort of algorithmic "who's who" (read up on its 
  ranking system to see what I mean).
