Tip Jar (114+ / 99-)
That pretty much says it all.
The diary with that tip jar was on the rec list for nearly a dozen hours, until it was manually removed by the admins. As expected with that number of HRs it contained patently offensive material. That's an embarrassment to DKos; it should have had no position on the main page.
DKos admin ought to apply some sort of cutoff - too many tip jar HRs and a diary can't make the rec list. 50 seems like a pretty safe number.
I'd argue it shouldn't be shown in the recent diaries list either. It could still be available in peoples' individual feeds.
I'm intentionally not linking to the original diary. I don't want it's content to distract from the issue of the rec list formula.
