Let us suppose 100 people, all active members of a forum, buy a certain product. Let us suppose this product has a quality problem affecting say 3% of cases. (As well, for simplicity I suppose that many more than 100 of this product have been produced). Now, doing the math the chance that not one of the 100 owners will have a faulty example is 0.97 ^ 100 = less than 5%.
Put another way, there's a more than 95% chance at least one (or more) bad example will be found and reported within this group. In other words, groups such as ours have a high level of power to detect faults, even when the problem rate might be described as "low".
This has its good side: problems are detected easily and early. Audez'e and other manufacturers are certainly wise to monitor groups like these for problem reports.
The flip side, many - maybe all - of the remaining owners may justifiably worry whether theirs is also faulty, even though there is nothing to worry about in fact.
But further, as we know in this example the problem rate is low, the chance of any one owner being able to locate a genuine problem unit conveniently near-by is low as well, quite understandably giving some owners grounds for doubt the problem exists at all.
Of course, I just plucked the 3% figure out of the air. I have no idea what problem rate there is with the LCD3. FWIW this example merely shows that even a small problem rate is almost certain to be detected and, quite properly, reported as a direct consequence of belonging to a large(-ish) group. Call it a cost/benefit of being a citizen of the internet.
