Everything has tags now. This is what we in the IT industry call metadata: data that describes data. Each entry in the blog can be given a tag to describe the content. I have spent a bit of time doing this, and you can click on one of the tags in the ‘Tag Cloud’ at the side of the blog to see posts that have that tag. This means you can filter on specific topics. The Picture Gallery in Windows Vista also allows tags for pictures, and probably videos as well (haven’t checked that). Do I really have the time and patience to go through all several thousand of my pictures tagging them all? Maybe because it would mean I could quickly filter all the pictures of me, or Hannah, or of Cowes, or of animals etc. Once you have an enormous collection of data, then tags can be very useful.
