As a long time Slashdot reader, I found the Beta terrible. The admins made comments saying the anti-beta crowd is a small minority, but I don't believe it is.
There were a number of comments discussing a boycott this week, and originally I wasn't planning on participating. However, I then had suspicions that the admins were downvoting-to-zero comments against the Beta and upvoting-to-five comments for it. While the former is arguably justifiable, the latter IMO is distasteful no matter how you slice it. So I find myself boycotting slashdot this week as well.
I'm hoping the admins drop beta entirely, but I'm not holding my breath.
