title: Like button - XFBML or Iframe
body: <p>I'm about to incorporate Like buttons into my web site - it'll be the first time I've incorporated Facebook fubctionality - and would like some guidance on whether to use the XFBML option or the Iframe option. It seems as though XFBML offers more flexibilty for the future, but a) are there any disadvantages to this approach, and b) is the HTML5 compliant version better still? Thanks. </p>
