First off I must admit I do not follow much anymore, but after redesigning an older site this came to mind regarding header tags...
typical page scenario with widgets... I use one h1 tag towards the top of the page for the 'title' of the widget. Below this I list the widgets features with those features being divided into categories with an h2 title. There might be five or more h2 tags because there are many categories of features for a particular widget.
Is there anything wrong with this? I remember watching a video by Cutts stating you should not have your page cluttered with h1, duh, but since h2 carries some weight is there something wrong with having lots of h2's? One would think this is the natural heirarchy.
