The LW community is in rapid decline and people have been leaving in large numbers for years. LW is probably in the terminal stage of decline now, not in the initial or even middle stage. If you think this isn't true you are in denial - all the poll data and post/comment data shows this to be true.

I used to be an active member of this group. This is my first comment in months. I don't know why other people left; I can only speculate and offer the reasons why I left. The reason I left was because I perceived (maybe incorrectly, I don't know) that discourse was being dominated by a handful of individuals who had very little interest in actual rational unbiased discussion and were more interested in forcing their views on everyone under the pretense of rationality.

I guess it's a lesson and a set of things to learn for the next LW-like site. It's a lesson in how quickly good intentions (rational discussion and questioning authority) can lead to the evaporative cooling effect and the adoption of extreme sociological/political views while pretending that this is not taking place.
