First, I got excited that a Slashdot thread started about The Big Picture. Then I read the thread, and realized the initial post threw out the word “ontology” and led, oh, just about everyone down the wrong path. Ontology is not included in The Big Picture. Move on, start anew, look at the feature, and decide whether it’s useful or not based on what it does, not some academic label that is misapplied here.
