As an outcome of this lively earlier thread, "What to Do About the Queue" which was chock full of good ideas - we've made a couple of changes.

Posts that have less than 2 votes after 24 hours will be discarded.

Posts that have less than 3 votes after 48 hours will be discarded.

This will happen once a day at the same time we do our usual daily queue discard.

We've also raised the queue escape level again, as the front page is still going through a complete refresh every few hours it seems. The new peak-time escape level is 9 off-peak is 8.
