Indeed, much has changed in the newspaper world today. But no editor worth his salt minimises the importance of the letters column. It is still regarded as a vital link between the newspaper and its readership. For, it is the only indication of a qualitative response to a news report or editorial comment. Several letters published on the same issue offer a more incisive insight into the public mood than 'scientific' opinion polls. No editor I have worked under used the word interactive, but interactive communication was precisely what such letters are all about.
