This is an interesting idea. The idea is that when shopping for products online, you tag the items you are interested in buying, the site then can show you (and everybody else) all the items that match a tag (such as “camera” or “nokia”)…
I can’t imagine anyone except the shop-keepers actually doing this, but I imagine if there’s a body of products and yours isn’t listed that it may be easy to tag yours up and have it thrown into the “tag soup”, so to speak, and so expand the product listings organically.
