Seconded.
I've been on this site since about 2001. The 'This site has gone to shit' arguments have been around that long too. However, in the past 2 years (since around the /. Beta fiasco it seems) most of the quality comments have all but left. 'Conservative echo chamber' kinda hits the nail on the head. The libertarian dog whistle / talking points get trotted out so often it's just boring now to read. Arm-chair economists with such deep insights as 'Don't like your job, move and get another one, dummy!' seem to be about the best the site has to offer now.
Why am I still here then? Habit mostly, I gave it up (and read Soylent) for a good while, and now I come back, thought not as often as before. As for reading comments, I guess I still do out of some hope that they might get better again...though my tolerance is lower I spend only a fraction of the time trying to sift through the Randian garbage.
