Amazon introduces 'Tagging'

Amazon is currently testing the Tagging of items. It seems as if tagging comes more and more into mainstream applications, which is really great; I for one can't live without tags anymore. I use TagBag frequently to keep an eye over the tags which I applied to my files, I use del.icio.us to sort my links, iPhoto to tag my pictures and so on.

Now with the forthcoming adoption of tagging in the mainstream media, I hope that the emminent implication will be a higher use of tagging options in the overall software landscape.
And then, someday in the future, we could filter all links, pictures, files, emails, comments, blog-entries, people and drinks tagged as mostly harmless in the blink of an eye.
