Most buzz-heavy tech neologisms bug me. I can't stand the word "webinar." In the late 90s, it was "e-everything" -- e-commerce, e-publishing, e-nough! I'm even tired of iStuff from Apple.
Most recently, Web 2.0 makes me cringe. It's not that I don't like Google Maps. I love Google Maps. I just don't know anything new from a term like "Web 2.0". It scares me a little bit: Did the old one stop working? Will there be a patch release or service pack for the 2.0 version in three months? What happened?
Joel Spolsky has posted an article to his blog that explains why Web 2.0 is the wrong thing to say. There was no New Economy in 1998, and there is no new web today.
