Significance of WWW2 and WWW3

Www2 Www3

[reneewood]

Can someone please explain the significance of the search results produced by WWW2 and WWW3 and why do people watch these results? I'm not sure I understand what they really do. Is there some order of events that first begins with those search results? Thanks,
Renee
