I'm not saying that it should be one-way. Rather than providing unconstructive and baseless criticism, everyone should maintain a minimum of respect for the people in charge, and any criticism of how the site is run should be handled in a professional and nonconfrontational manner. Instead of using a "you" statement, use an "I" statement. Example with an actual criticism I have of people on here:
Unconstructive "you" statement:
"All you anti-POWER architecture users should stick to AROS if you want x86 AmigaOS and stop squeaking at the OS4 and MorphOS crowds!"
Constructive "I" statement:
"I disagree with those who deny the hard work of Hyperion and MorphOS developers to provide NG Amiga platforms by saying it should be on x86. Instead of directing how developers should spend their time and criticising design choices, they should offer their own skills as developers to the AROS project, which targets x86 development, or else contribute money to that project to better it."
Considering the fact that this patronising tone in the first example is practiced by many people on this forum, and that more time is spent arguing on things rather than offering anything constructive, Im surprised the banhammer isn't more widely used. Don't be a jerk, be constructive.
