As Kathy would say "here's the thing"... some of the comments may seem negative to some people, but they are not necessarily negative. At the end of the 7 announcement post, the creators asked for input about bugs, problems and wants.... soooo... that is what they are getting. It does not mean that we do not think they are doing a great job. However, suggesting new features or noting problem areas will save them a lot of upgrade time in the future. Those that say "great job" without see more pointing out any negatives, will have to put up and shut up in the future.
What is so wrong with pointing out problem areas like the menu bar, which is a great idea but needs work. Nothing that I can see.
Member of my networks will always complain, but I take it as helpful suggestions rather than regarding it as an insult.

In the end result it also helps ourselves and others to better understand either the limits of the software or the possiblities.

Personally. I say keep on with the input. Good or bad. Maybe I am just too, too American but most of us really BELIEVE in our 1st amendment rights.
