== i need advice to help me get some perspective == 

 I am not angry with you. i am frustrated beyond belief. wiki has been irrelevant in my technical field. the information was inaccurate at best and fundamentally wrong all to frequently. bluntly, popular science had a better reputation. then i hear wiki wants to improve its academic credibility. so i make an effort. after my first bumps and bruises that you nursed me through i venture off on my own. what do i discover, sales literature. all i see is an endless accumulation of salesmen trying to get their products noticed. with the exception of 2 wonderful contributors, no one has made any effort to clean up the mess that exists in the sum total of turbomachinery. those 2 wonderful contributors are gone. their articles are being destroyed paragraph by paragraph. wiki is the best of ideas.  
 please help me get some perspective.  
 is there a team of tech specialists and mathematicians that these changes can be brought to to judge?
