nerdwatcher 

a person who pays close attention to the activities of members of the internet and telecommunications technology community. nerdwatching is facilitated by emerging applications through which members of this community can report on their activities (e.g. twitter, qik.com). these technologies are a common focus of members' attention, as are the reports of other members of the community resulting in a feedback loop, in which nerds feed information to other nerds, the audience and participants overlap, and nerdwatchers beget nerdwatchers. see also metanerd.

Netwatcher 

(1) often pejorative. Compulsive websurfers who rely on Internet resources as their sole source of information. Often carries a connotation of anti-elitism and a disdain for more tradional "paper-based" sources such as newspapers, encyclopedias, research papers, peer-review publications, or books.
(2) Professional commentators - marketing and media specialists - who track online trends, netiquette, and usage patterns in order to identify changes in behavioural patterns

Militant Wikipedia fans make up a particlarly virulent cult of Netwatchers.
