I always check top 50 on a map to see the rates of people being able to modplay>S>no-S it. It's a fast indication of how hard a map is. For example:
http://osu.ppy.sh/s/42909 - only top 19 have S = hard map
http://osu.ppy.sh/s/53853 - all top 49 have SH, but at 50~ modplays stop.
^ being able to see top 100 on that would help see how hard it is for example. I'd find this useful a lot. Only gave two map examples but I check top 50 for every single map.
Also it's interesting to see whether you spot people you recognize in the top players, especially when you know it's people who can S that map. If I fail to spot a player in top 50 of a map when I think he can get there, I might recommend the map to him, because it's most likely he hasn't seen it at all yet or else he'd be there. Again top 100 would help for this for more contested maps.
