I wonder if it might be worthwhile approaching Manu Sporny about putting in a proposal to talk about rdfa, microformats, his recent work with json, or something else relevant/timely that he thinks might fit?
As Dan Brickley pointed out recently [1], the semweb/ linkeddata crowd really share 99.9% of their geek DNA with the microformats community...and Manu has done a really great job bridging the two communities. Microformats have been a popular topic at past sxsw conferences. Thanks for continuing to push on this Juan. //Ed [1] http://lists.w3.org/Archives/Public/public-lod/2010Jul/0020.html
