Constructive criticism would be nice though, right?

Sure, but that wasn't my point. I was rebutting your statement. I was not saying what would or would not be nice.

Honestly, I have a completely different read on the content of the comments on this page. I think you are going out of your way to find "pejorative" and "destructive" comments. The majority appear to be pretty well thought out by my eyes. Most people seem to be questioning the efficacy of openbook's approach to the problem. It is obviously something people care a lot about and there are a lot of very legitimate issues with openbook's approach that have been discussed on this page.

You quoted a piece of my comment out of context and then said that "putting effort into something does not insulate you from criticism".

I never said that.

I said that the comments I read up to the point in time when I wrote my comment looked not exactly constructive or helpful.

I agree that later some people made up their minds and contributed helpful criticism.

That does not invalidate my point though.

Maybe we wouldn't have to deal with things like FB anymore if qualified people would use their time to come up with a solution instead of pointing out what does NOT work all the time.
