I'm in the process of building a social site and I was wondering if microformats are still relevant and or useful? Should I bother implementing them?<p>Thanks!
Microformats are still supported, but they've been replaced by HTML5 microdata. If you're developing a new website, microdata is the way to go.<p>The microdata schemas supported by the three major search engines are documented at <a href="http://www.schema.org" rel="nofollow">http://www.schema.org</a>. Also, Google still supports microformats: <a href="http://www.google.com/support/webmasters/bin/answer.py?answer=99170" rel="nofollow">http://www.google.com/support/webmasters/bin/answer.py?answe...</a>
Google, Bing and Yahoo! have recently started <a href="http://schema.org/" rel="nofollow">http://schema.org/</a> a shared markup vocabulary based on microformats.<p>If some of your data can fit in one of those formats you could benefit from a enhanced presentation in the search engine results pages.<p>Example: <a href="http://schema.org/Recipe" rel="nofollow">http://schema.org/Recipe</a> — google "spicy pork recipe", I see some results with photos, calories, etc.
