Well, this hardly constitutes a trend but take a look at member L.J.G. in the very thread being cited by the OP. His first review was the day he signed up. He has then continued to contribute and post images over the last year.
As noted, the L.J.G. post is a year old. It is also consistent with the overall trend of 15-85 reviews.
CGrindahl eloquently outlines the progression that I think many of us follow as the light dawns that FredMiranda.com is a truly unique place.
At the top of a long list of precious FM resources is the willingness to share experiences and expertise as well as images. Look at the workflow posts by Conrad Tan, Tim Kuhn, Imagemaster and MANY others. I guarantee the expertise they shared on FM became the outline for profitable seminars and training courses. This in addition to countless ideas, tips and smiles along the way.
Lastly, this post pointed to what I saw as problem. Some might agree while others disagree --- I\'ll support Fred\'s decision as to what, if any, action is required.
