A problem with anonymous forums is you don't know whether to trust the stories. At best we end up with something like Wikipedia where all facts are copied from other sources.
At which point, you're drawing a conclusion. I like to hear people's stories and firsthand experiences, too. They help us get into the shoes of someone else and get a new perspective. However, I take them for what they are: anecdotes. If we want to draw some conclusion or insight from the data, then we must apply reasoning.
To put it another way, a well-written argument often calls on evidence that can be interesting and useful even if you disagree with the conclusion. But the conclusion of an anonymous commenter can't be trusted without the supporting evidence.
And yet, many people think that if they state their conclusions louder, or turn them into a clever slogan, others will be compelled to listen to them. This happens especially when these conclusions become "conventional wisdom" in some community.
