The negative comments that you support *do* depress people (I apologise for the word 'everyone' - some people may, perversely, appear to thrive off it). Like the article that we are discussing, criticism needs to be balanced - and based on knowledge.
In my experience people respond best to having their positive aspects praised and help given to improve the rest. You criticise RISC OS magazines. That criticism would be best made by being made by someone who read the magazines, made a correct statement, produced a balanced review to show how it should be done, and passed on positive suggestions to the software publisher to improve the program.
That's how people of goodwill can help make a positive difference to this market.
