Edwin Jonk: I don't think multiple h1's is best practise. But in this case the h1 is the logo. What should be the h1 is wrapped around <font>. Which is quite strange, because the advice is to use css for that. And since they define it as HTML5, it is no longer valid HTML.
Although most browsers can handle this - and Googlebot does not require 100% valid HTML - ;it would be something on my list to fix.
Dave Elliott: multiple h1's are fine in html5! At least from the development side of things.
;On the SEO side of things its worth baring in mind that multiple h1 tags will compete against each other. So h2, h3 may be more appropriate unless the page is genuinly about more than one thing(in which case, why isn't it a separate page?)
