In my view it is important that people speak the truth as they see it. Negative comments can and often are constructive. Imagine someone comes on here talking about a new item they think they are going to make and possibly sell. People generally think it is rubbish but don't tell the OP this, The person goes into production and no one buys it. Not good for the OP.

As for the being nice comments most people on here have been nice and horrible to different people at different times
