I was Technical Editor and Chief Correspondent to the UK's Diver Magazine when it was run by owner Bernard Eaton with old-fashioned British journalistic values. The advertising department hated me whenever I upset an advertiser (which I did often) but Bernard Eaton told me to keep doing what I was doing and we built the monthly circulation to an unprecedented 55,000 and we got a lot of things improved in the diving industry. Alas, Bernard died, times changed and I resigned after 26 years because it began to be advertising-driven like all the other diving magazines.
Ben Davison got to hear and offered me an editing job - but I am disqualified from going on any dive trips for Undercurrent because I am too recognizable in the industry. I can confirm that no resort, product or service pays for a favorable review or otherwise.
There might be a few banner ads here and there but Ben Davison jealously guards the integrity of the newsletter. Any resort that says resorts pay for a good review is likely to be one that got a pasting and say that out of bitterness or jealousy of rivals.
Readers can also post their own impressions and if you are going to somewhere, it's best to read a range of these to get a realistic idea of what a place is like. There are now thousands of these available to subscribers on the html site.
Undercurrent newsletter is by no means perfect but there is a team of people doing their best to make it so. We also try to present both sides of every story. It is a labor of love for those involved. (We sometimes get things wrong but are never too shy to admit it and put in a correction.)
People subscribe to get it but remember that old New York saying: If it's free it ain't worth nothin'.
I hope that settles things.
