No doubt the real reason for the dip is that everyone was more focussed on Christamas gadgets than they were on Web 2.0 widgets. Either way when the terms use finally wanes it is more likely to indicate that it has moved from buzzword to everyday jargon and that the time has come for a more reasoned assessment of the usefulness of Web 2.0 RIA's. When the dust settles it seems fairly clear that we will be left with some very useful tools and that the web will be littered with enumerable oddly named corpses.
