No ruckus is required. As we commented before, the thumbs down was instituted as a trial, which means we'd try it out and see how people liked it.
It seems that the feedback on the thumbs down is fairly universally negative, though we'll probably conduct an official poll to give folks the opportunity to weigh in after they've had a chance to see how it works in "real life."
We'll be addressing thumbs and other questions after the development team works their way through the list of remaining glitches to fix since the first priority is to get everything working properly (search is fixed, but needs a small tweak; email notification still aren't going out; thread views wonky, etc.)
Thanks for taking your time to provide your input here. We're going to close this thread so folks are more likely to see this post/explanation, and we'll post a poll on a new thread later if necessary.
