Posts unless extremely well explained will get modded down to troll
And there, I think, is the rub. If you have a point to make that runs substantially counter to conventional wisdom, you'd better be prepared to have it very well worked out.
A lot of non-down-modded posts aren't particularly well-written, either, and it's entirely possible for basic pap drivel to be upvoted simply for pandering. But it's relatively easy to ignore such things while looking for something that actually is insightful. For me, at least, it's a different experience from things designed to upset me: they DO upset me, and that's not as easily dismissed. That's my weakness, perhaps, but it's real, and common.
It's my belief that an unorthodox but valid idea will eventually find a voice that can express it well, and that when that happens, it will be considered. Until then, I'm willing to take the risk that if an idea is widely disbelieved AND badly expressed, it's probably because it's wrong. Given my limited time to spend looking at web sites, it seems the best strategy.
If it means I'm not the first one to hear about some brilliant idea or nugget of news, that's actually OK with me. I know that there are others who have more time and patience, and so I have no time or patience for people who insist that the sole reason they're being modded down is because they're unpopular. They need to seriously consider the possibility that they're wrong, and one strong clue to that is an inability to phrase the argument cogently, in a way that resists easy dismissal.
