I've been a member of the "Slashdot community" for quite a long time (my user id is 583). Over the years I have witnessed a steady decline in the quality of discussion. The vitriol has become so scurrilous of late that I have decided I'll no longer visit. Reading the following comments (particularly those with a "5, Insightful" score) will clearly demonstrate this.
Slashdot | U.S. Rejects Canadian Rejection of DMCA
(The comments about balls and Condoleeza Rice are particularly "insightful".)
UPDATE (Tue 03 May 07:36:39 JST 2005):
I ran across the Quit Slashdot.org Today!
campaign. The Top Nine Reasons to Quit Slashdot.org
were all excellent, but I particularly liked number 1 (I've had that guy ignored in my /. prefs for years). Check it out.
