The newest questions page seems to be caching for much longer than it used to (multiple minutes - sometimes more than 10 minutes).
I have seen this happen when the site updates, but it has been like that for a while now.
Was the cache expiration changed to expire less often? Is there an infrastructure issue here?
BTW - I am using 50 results per page.
Please reduce it to the more friendly 1 minute/30 seconds (or so) that it was.
Update: A guess here, but it looks like it caches a page until a pagefull of newer results come in.
