Accentuating the positive

As editor of trade title I receive many case studies from suppliers wanting to demonstrate how good their products and service are - and I upload them unedited and clearly marked as such on our website and on newsletters because that’s expected these days. For obvious reasons there is practically zilch negativity in any case study submitted. Given that, how useful do you find such stories? Does that knowledge impact how you deliver your own case studies and market your own products and services?
