I think its a measure of the paucity of Software Engineering as a discipline that a intelligent and motivated person as the parent, is unable to find any research later than the 1970's

(It seems to me that most software research stopped as the PC revolution took off)

It seems to me that software research moved out of the Hallowed Halls of Academia and into the nasty pizzabox-laden basements of geeks' parent houses, where thousands of people hacked (no chicken involved) on massively capable inexpensive hardware.

Clearly you didn't read his post, because several of the links were published since 2003.

The fact that there are studies ranging from the 1970s to the 2000s is actually one of the reasons I find this so interesting.

Communications technology keeps getting better - yet co-location still seems to carry a major advantage. That is interesting to me.
