Monbiot writes comment articles about as often as Boris, and makes a living from journalism like Boris.
But compare
this first sentence, from his latest blog entry (guardian website tuesday 13th nov):
"Loth as I am to threaten my reputation as a bilious old git, I feel compelled to shock you."
It's sort of like the first sentences of lots of Boris' articles... only much, much better.
People admire Boris' writing style. I find it hackneyed.
