Real Time Collaboration and Web 2.0 tools, tips, and reviews

Tara Hunt is also talking about designing and programming for users.  Real users. 

I really hate the phrase, "I want to design this for the housewife in Utah," because the housewife in Utah may or may not give a damn about how you can tag photos. She may or may not even have a digital camera because the film one isn't broken. And she isn't uninformed, she is totally right.

This discussion seems to be bubbling up to the blogosphere's consciousness. Is is product of the fear of a 'Web 2.0 bubble' or a genuine call to arms?
