All points taken. I confess I spent about a half hour typing in IDNs, mostly to discover that all the obvious ones are taken. Still, there must be less obvious names that are on the rise. When the Japanese catch up with the idea, and when iMode finally merges with the rest of the net, there may be a huge return. I will start looking at them, behind the curve as I obviously am.
The internet was used for things long before "the web" was put on top of it.
Email, gopher, ftp, etc.
If you ask me, Web 2.0 was in 1994 timeframe when graphical browsers and search engines arrived. Did you ever surf with the text based browser "lynx", from site to site as the only form of navigation? Web 2.0 is a term that was coined by people who weren't part of Web 1.0.
