You are given a passage. You need to construct a question about the information present in the passage. Construct a question in such a way that (i) it is unambiguous, (ii) its answer is the whole paragraph. Avoid creating questions that can be answered correctly without actually understanding the paragraph.

Tags are like post-it notes that readers of the content leave behind for other readers. They give clues to the context and meaning beyond a simple description. They're like finding notes in a text book scribbled by a previous owner. You can usually gain insight into the material based on those notes.

Now imagine there is a cross-reference of all those post-its and margin notes. More than one person can add their own post-it. You can easily find the most popular "post-its" thanks to an index of all of them. This is where the real power of tagging lies-- in the weight and meaning these agreed-upon notes give.

Of course, context is everything. Next time you're together, show her MyWeb2.0 and del.icio.us in action. Show her how the information is sliced and diced-- most recent, most popular, most frequently used tags. I find my parents only get these new paradigms when I show them to them in context.
what is a tag, and why is it being hailed by some people as the greatest thing since sliced bread?
