I have done it on another forum site. It is not that I feel people do not care about what I say. It is that fact I feel uncomfortable with revealing to much about myself. On the net as well in real life.
That's funny because my brain works exactly the opposite. I feel like my stupidity stands out in a thread with few posts but has better chance to go unnoticed in a popular thread. But considering what you just said, now I'm questionning my logic.
