PS: Anyone have better ideas for renaming Web 2.0? Seems like 2.0 just means anything you can tag or build in Ajax. Woohoo. It's still the web, the one that's been around awhile now, with many versions and upgrades improving its maturity (hardly just 2 versions - though some may say it's still in beta, or alpha).
