The written version is a heavily edited concatenation of those two talks. Today I want to talk about categorization, and I want to convince you that a lot of what we think we know about categorization is wrong. In particular, I want to convince you that many of the ways we're attempting to apply categorization to the electronic world are actually a bad fit, because we've adopted habits of mind that are left over from earlier strategies. I also want to convince you that what we're seeing when we see the Web is actually a radical break with previous categorization strategies, rather than an extension of them. The second part of the talk is more speculative, because it is often the case that old systems get broken before people know what's going to take their place. (Anyone watching the music industry can see this at work today.) That's what I think is happening with categorization. What I think is coming instead are much more organic ways of organizing information than our current categorization schemes allow, based on two units -- the link, which can point to anything, and the tag, which is a way of attaching labels to links.

The action principle of Levitra is based on the drug ability to block the activity of the enzyme, which contributes to an increase in the tone of the vessels of the penis and their narrowing. Levitra administration promotes a relaxation in the smooth muscle of the corpus cavernosum vessels and dilation of arteries, which results in an increased blood flow into the penis. Filling of cavities of the cavernous bodies with blood results in an erection, which gives the man back his ability to have full sexual intercourse.
