Many good points. But I might add it's not always helpful to let such posters get your dandruff up to the point that you have to share your displeasure with the posters and/or their University. It's easy to prejudge and make assumptions and end up responding like so many posters use to do on the avrfrecks site and end up with the site gaining a reputation of being unfriendly and not willing to help new comers.
I share many of the negative comments posted here on many of the request for help, but I really work at just reading such posts/requests and moving on to what I might prejudge as a more worthy question or posting. Life is too short to spend being frustrated unless you really have a solution to share.
One token 'Grumpy' is enough for any one site. 
"Goggle Engineering" I love that term. 
At the refinery I worked at before retirement we referred to '"Smoking post engineering", and it wasn't always a negative term. I knew one engineer that said any time he got stuck with a problem he would go sit on the toilet for awhile and a solution would always seem to pop up or out as the case may be.
