Question: The new HTML5 article tag all seems very great and wonderful and there has been much discussion here and elsewhere about its uses.

Unfortunately, all this discussion seems to be in the context of blog or news sites where the content is all just that, content.

In an ecommerce site, the biggest question to be asking is, how do I now mark up a product? 

Taking the spec for guidance, it seems that a saleable item is indeed something distinct that could be syndicated (and often is). The article tag seems like a good match, yet I see no mention of its use in this way.

Is it appropriate here but all the examples blogs etc. because they seem to fit a bit more intuitively with the name of the tag? Or am I stretching too hard at the spec?

Any guidance would be much appreciated.

Answer: 
You should take a look at [this article](http://peteschuster.com/2012/05/semantic-html5-for-products-in-ecommerce/#comment-878)

Looks like `<article>` is not that bad an idea. I am using pointers from [here](http://peteschuster.com/2012/05/semantic-html5-for-products-in-ecommerce/#comment-878) and <http://schema.org/Product> for an e-commerce site project.
Having custom tags bothers IE a lot and we can not ignore the internet explorer yet.
