I was wondering if anyone here has looked into RDFa. I believe it has a lot of potential to increase traffic to your websites. If you don't know what RDFa is then you can check out this wikipedia article: http://en.wikipedia.org/wiki/RDFa
Yahoo has been using RDFa for a little while now to show enhanced search results. Google also has recently incorporated a limited implementation of RDFa in their search results. Unfortunately, Bing doesn't seem to use RDFa at this time, but hopefully they will in the future. Google and Yahoo use the structured data to display enhanced search results. Enhanced search results have been shown to attract more interest, therefore driving more traffic to your site. So do you think it's worth trying? I've been messing around with implementing RDFa via bbcodes on a phpBB forum and it seems to work well. I'm still waiting for my pages using it to get indexed, so we'll see how that goes.
