Hey look, bump of a four month old topic by people who aren't qualified to open their mouths on the subject... since that psd2html5 website is a poster child for everything wrong with such designs and a stunning example of everything I typically rant about when it comes to inaccessible design, much less why HTML 5 is a bunch of idiotic BS I cannot fathom how anyone is DUMB ENOUGH to want to use. Illegible color contrasts, fixed width layouts, absurdly undersized fixed metric fonts in the content, gibberish/nonsensical heading orders, metadata/itemprop asshattery just bloating out the page for nothing, comment placements that could trip rendering errors, IE cc's for nothing, etc, etc... If their site is any indication of their work, I truly pity anyone duped into using them for anything. Just another nube predator. Though that all goes hand in hand with anyone advocating the dumbass back-assward "draw a goofy picture first" method of site development.
Look... I never said that I used them since I typically do things myself. I was trying to add something relevant to the conversation.
