I've been a huge advocate of downvotes, but I stopped using most of mine due to some of outrageous downvotes of the large accounts and trails.

Most of us will handle a downvote or two with dignity and class, but when one group decides another is bad and has a huge amount of voting power, I was turned off quickly.

I also think that SBI was a great project and I think it is clear anytime you look at Trending that curation isn't about quality, so I have no idea what the puritans are fussing about some projects like SBI that does good work and helps with retention is.
