(Adding the SPARQL query for the geeks is also possible...)I wrestled with this one quite a bit. In fact, the mention of SPARQL is in there in the first place because Michael prompted me to do it, and I eventually agreed that hinting at the power of SPARQL would be the right thing to do.But, thinking back to my earliest experience with RDF... I would not want HTML authors to have to grok an actual SPARQL query right away. I think the abstract power of "you can query this stuff" is enough.However, I think your point about binding the abstract SPARQL to the example is correct. How about "friends of Alice's who created items whose title contains the word 'Bob'" ?
Well, it could be even more down to Earth for outsiders: Bob can create a similar graph of his social network, and you can trivially use SPARQL to answer the question: what friends have Alice and Bob in common? Of what are the email addresses and/or homepages of all those common friends?

(Mini, mini comment: if you want to refer to N3, you should rather refer to the team submission. Either N3 or Turtle...)Sounds good. Both updates have been made to the live version. -Ben
