I think this is one of those grey areas. I like my editorials to provoke thought, not to advertise. In this case, I think there is enough substance in the editorial for it to work, but I think it's a pretty close run thing. Taking the editorial in isolation, I'm glad I had the chance to read it, but I hope this doesn't signal a subtle shift towards using editorials as an extra bit of advertising real estate in the daily newsletter.
