Pam came up with an intriguing blanket term for delicious, Flickr, GMail, blogging, and the rest of Web 2.0: webology.
My mom had a couple of interesting names for this: internet guy, fanatico.
Update: I'm getting closer to a name for this space. It's what Barlow is talking about in his "Declaration of the Independence of Cyberspace": "Cyberspace consists of transactions, relationships, and thought itself, arrayed like a standing wave in the web of our communications." I don't like the term "cyberspace" -- it is fairly worn out these days. But Barlow's meaning is what I'm after. So what is a more up-to-date term for the utopia that Barlow is describing?
Internet? That's the foundation on which the city is built, not the city itself.
Web 2.0? Closer.
Internet culture? There are several different areas of interest on the internet, each with their own culture e.g. The geek culture, the online-dating culture, the gaming culture. I'm looking for an overarching term describing the whole.
The online lifestyle? Better, but it needs more precision.
The cyberspatial utopia?
Update: I've figured out a name: Personal IT.
