It's been almost two months since some major changes were made to the Hot Network Questions (HNQ), including a timeline event when a post hits HNQ, a (configurable) maximum number of questions each site can have at a time in HNQ, posts ageing out of HNQ and moderators being able to remove questions from HNQ.
The last paragraph of that announcement states:
We know that there's still work to do but these changes will address the most immediate needs and give us the information we need to make changes in the future that are based on data rather than anecdotal evidence.
I'm wondering if some of this data has already been collected, and can be shared. Are these changes are already having some noticeable effect; have they actually changed anything since being implemented? Did these changes, for example, lead to differences in the number of questions on a site that hit HNQ, the time these questions spend on HNQ, site traffic, or perhaps even post scores? Is there a number of people who have used their profile settings to turn off HNQ entirely, and is there any decline in traffic as a consequence?
