I'm lost... help, please!

A thread for questions, clarifications, confusions, frustrations, and general mind-boggling. Are you confused about terminology we've encountered in our reading? Puzzled by something Alenda mentioned in class? Don't be afraid to ask for help here and we can all exercise what Pierre Levy calls collective intelligence.

From last week: HCI, GUI, avant-garde
From this week: cybernetics

Guess who sang these apropos lyrics?

Help, I need somebody,
Help, not just anybody,
Help, you know I need someone, help!

When I was younger, so much younger than today,
I never needed anybody's help in any way.
But now these days are gone, I'm not so self assured,
Now I find I've changed my mind and opened up the doors.
