Most Self efforts has been on decomposition of Objects in more
 atomic parts (as an extensive aplication of OO concepts).

Most Smalltalk efforts has been done on composition/building
 of objects systems.

Decomposition and searching for atomic elements of (de)composition
 is interesting for people that are learning how to apply Object Oriented
 method (isolation+encapsulation as a axe to disect the world
 in "solvable objects" / problems).

Composition is interesting for architects (the fat world of
 "components" asembly :)

Building of Organic systems (open and with internal organs in dynamic
relation)
 is interested for people facing real [*] system development.
Smalltalk is appropiate for this kind of development and in this way has
 a very important place in the future of informatics.
[*] real as opposed to formal/ideal systems. Like in physics real/ideal
gases.

The decomposition in more atomic elements is related with simplicity
 and "beauty" of formal definition; but is not related with
 major potential to build real systems.

cheers,
Ale.
