Hiya,<p>I posted an Ask HN 4 days back (https://news.ycombinator.com/item?id=6290198) - it stayed on the Ask page for 2 days and slowly slipped to the next page. However after 12 hours it came back to the 3rd spot on the Ask page and then slowly slipped away again. Today again its back in the 9th spot, along with quite a few old Ask HN.<p>I am not complaining (obviously) - but I do remember loads of other Ask HNs being posted after mine (with lot more points and comments).<p>Is there a reason for the algorithm to be doing this? Is it random or some specific logic?
