The New York Times reported, "Mr. Walker has raised dull blogging to an art form by meticulously chronicling mundane events in his life: checking e-mail, turning his head to the right, walking past the ironing board, and thinking about making some food. His minimalist musings have attracted something of a cult following, with his blog (www.wibsite.com/wiblog/dull/) counting about 85,000 page views a month. Seldom has dullness generated such keen interest."
His cartoons have a similar wry, unexpected quality - he turns his humour towards such subjects as What Your Pew Says About You, When to Stand Up For a Hymn, Flags on Church Towers, The Dangers of Arriving Too Early or too Late, and other uneventful aspects of life in local churches.
