It depends on whether you want people who are direct and without a cross-purpose, or you want to hear what you want to be told.
At any rate, I got 18 people that thought I contributed something useful. Which, by the way, on a percentage basis, is considerably higher than yours per post.
By the way, you answered your own question. If I can correct something someone said, to me that's a positive thing. The fight against disinformation is an important one, I think. Maybe not to you.
My motivations are not to pick fights, but, I say what I think. If you put any two people in a room, I'll guarantee you'll have two different sets of opinions. It's normal, and probably healthy, for people to disagree. If that's "fight" to you, your definition differs from mine.
The whole crux of this is you made a poor comparison between someone that legitimately said the Cimex didn't do as much cleaning as other methods, and past quotes, some of which were taken out of context, and all of which were wrong. Correcting your premise and articulating those quotes in context may have seemed negative to you, but, that's a matter of perspective, really.
Like "rich" says I guess that's a matter of perspective.
I hate to swallow my pride but if Ken Harris is the inventor of the glide then kudos to him. Regardless of your opinion of him and his business practices, that was a stroke of genius. The message boards, ICS was the first I saw, then Mike Paitoilette starting *********** allowing cleaners to really express their opinions. But my favorite development this last ten years is my Garmin Nuvi that has that nice British woman telling me how to drive to my various jobs, and even telling me what side of the street the house is on.
