I actually lurk a lot, and I often read every 50 scores and try to find something interesting. Also, showing scores between 50 and 100 could lead me to find some double time play without full combo in a map that no one in the top 50 has double time. But that's just me.
Edit: For example, until today, in this map http://osu.ppy.sh/p/beatmap?b=122075&m=0#scores penew was #50 with double time, and it was impressing, now it's gone forever.
