Great post from Joe McKendrick about the dangers of Web 2.0. He quotes David Chapell:
"Some of those Web 2.0 applications will fail, with an important
piece of the user interface just not showing up one day because one of
the supporting feeds just isn’t there any more. The guy who mashed it
up in the first place doesn’t work there anymore, and many will be
scrambling to figure out who is supposed to fix it, and who to point
the finger at."
