Let me just say first that I’m not looking to start a flame war 🙂
I’m aware of the semantic meaning that tags such as <article> give a document, but what benefits does one get from using them?
Do search engines look at them differently? If not, what other benefits are there?
A Q+A on Google’s Webmaster Central seems to suggest that the new HTML5 semantic elements have no impact currently, but will at some point in the future:
