I agree with your thinking.
For me, I have been OSO since the beginning and I like to be informed, about the good/new products/services, but also about what went wrong, what doesn't work and what works regarding performance gains and the interesting experiences members have had. The more information the better, I like to be informed when I can.
If there is an accident, product failure, ripped-off situation, that is not bashing at all, if the facts are accurate and honest, that is called a negative review and is common to all business. That is the internet, good reviews and bad reviews, all business are not immune to bad reviews. You can't please all the people all the time, so a negative comment or bad review is inevitable. Get used to it, it is the day and age we live in, I just don't like when someone posts his or her opinion and the bashing on that individual takes place, and the name calling starts, and the character assassination takes places because someone posts an opinion on whatever topic that the in-crowd disagrees with starts blasting that person. Treat people the way you would like to be treated.
I really liked the post (#38) in this thread about the big room, and would the person posting say the same words to another person face to face? If yes, then it is OK. If no then the litmus test is, "would you get your ass kicked if you said the words (he or she posted) in a face to face situation why then is it suddenly appropriate to hide behind a keyboard?" If someone would would want to kick your ass in person because of what you said you would think twice about saying it, and the same should apply, again with, treat people the way you would want to be treated.
I really don't like all the negativity, but I have a choice, I can read the thread, or ignore it and usually I ignore it as you see by me posting only 941 times in almost ten years. But JC is right, I hate to see a business smeared when there are two sides to the story, fair balance (both sides) to an issue is necessary for an for honest opinion (by me the reader), and with all the facts we the readers can make an intelligent and informed decision on whether a person has a legitimate gripe or is being over-top/complainer.
