Hi Ian

no its not needed see this discussion http://lists.w3.org/Archives/Public/semantic-web/2007Jul/0086.html pointing to 203 406 or thers..

..but a number of social community mechanisms will activate if you bring this up, ranging from russian style "you're being antipatriotic criticizing the existing status quo " to "..but its so deployed now" and ".. you're distracting the community from other more important issues ", none of this will make sense if analized by proper logical means of course (e.g. by a proper IT manager in a proper company, paid based on actual results).

But the core of the matter really is : who cares. My educated guess looking at Sindice flowing data is that everyday out of 100 new sites on web of data 99.9 simply use RDFa which doesnt have this issue.

choose how to publish yourself but here is another one. If you chose NOT to use RDFa you will miss out on anything which will enhance the user experience based on annotations. As an example see our entry in the semantic web challange [1].
