As a two year participant in MS, I have mixed feelings. Here's why:
The anonymous nature of the site can lend itself to a lack of civility when things go sideways due to either misunderstanding, misinterpretation, misspelling, or sometimes just a strong difference of opinions. I've learned to try and avoid writing anything that anyone might take the wrong way.
Some long time members are very friendly, like @carusoam who I'm sure everyone will agree is immediately welcoming, and I agree should be considered the "Dean of MooneySpace".
In my opinion, this site should abandon the anonymous model. It will promote civility. Anonymity brings out the worst in some people.
Secondly, this site should include a FAQ where longstanding threads addressing common and widespread issues with our aircraft should be posted. Using google to search site:mooneyspace.com frequently turns up a discussion of almost any issue I have. A thread with hundreds of posts, on a common problem, that is discussed to the point of the equivalent of a peer-review journal paper, should be easy to find. Sites usually do that by establishing a FAQ section. That will require one or more active moderators.
Finally, I have learned a tremendous amount. A good search using google will often show that someone else has been down whatever road I find myself on. If the answer is not there, or if technological change is the issue, then a well-worded question will often elicit great advice. The professional folks who participate on MS are often very helpful with regards to mechanical and/or maintenance and/or insurance advice. @Clarence , @Cody Stallings @M20Doc and @Parker_Woodruff immediately come to mind. They really help our community and I suspect that many of us have gained from interactions with them and other professionals that choose to answer our questions.
My 2-cents worth.
