User communities, per se, are not a new phenomenon. They have existed in the real world for years, but in more passive forms.
Wherever there are products, there are users, and inevitably users would get together to discuss their experiences with the
product. Housewives deriding the local grocer, students comparing the attributes of their pens, and even office-goers arguing
over the usability of a particular brand of laptop are all user communities in their most basic form.
