It has been one year since I cancelled my subscriptions to The New York Times and the Los Angeles Times . In that time, I continued to read both publications online. My assessment of this experiment is that reading newspapers and journalism online is vastly inferior to the hard copy thrown on my porch each morning. So I restarted my subscription to the Los Angeles Times and I have made it a point to buy The New York Times as often as I pass one of those coin boxes or my local news stand.

I've always looked upon Nigel Farage as an English amusement. He reminds me of rows of fair-ground clowns that amused me greatly as a child in Australia. The heads swivelled constantly to the left and the right, and the trick consisted of guessing the exact moment to drop your ping-pong ball down the clown's throat, so that it ended up falling into the right spot and winning something. Today, I don't think the prize would justify my efforts. On the other hand, the ping-pong ball might shut up Farage.
