“Today is the second anniversary of tags”– this is what the Technorati newsletter announced today. The newsletter also said:

The beauty of tags is that they’re metadata: data about data. What does that mean? Tags actually describe (or categorize) their subject, as opposed to, say, keywords, which just occur within them.

We think tags are becoming popular because on the Live Web, categories and topics are just as, if not more useful than keywords for describing and finding content, especially when that content doesn’t contain lots of text (photos, videos, songs and the like).

The folks at Technorati are celebrating the day and the achievement. It’s only natural to express joy at such grand success — after all, tagging goes beyond blogs. It’s Web 2.0 meets usability meets The Users.
