Hopefully the algorithm will improve over time - compared to the site which shall not be mentioned, I find that Hot or Active tend to show the same articles for days (despite there being plenty of newer content). Top Day works well the first time I log in for the day, but then that gets stale too. On the front page I feel like I need more like a "Top Hour" option ... so I can see what is new without the "drinking from the fire hose" that is "new".
These are the early days, Im not unhappy with where we are, I just hope this remains a work in progress and improves.
