Since there is so many facts just bombarding all of a sudden,i think you should make a dunno how to put this,a highlight.
You see,since too many facts been posted already,people might not scroll down and they miss the one that was previous posted before.(well it a problem for me, i don't know for the rest of you guys.)
What i suggest is doing a highlight. This could work by every two weeks and you could highlight the facts that are very interested.
You have done it before and it would be nice for the people to view the previous interesting facts who have just gotten to visiting the site or missthe prevoius ones.
