What's to keep every player from making a spout lore check when they are stopping to ponder the Tribes & Towers of the world?

Is the GM expected to improv a seperate possible thing know for each player/class/race combo at the table?

Am I not understanding the move?

Should you only allow one check per instance/area?

I just don't want to run into a situation I find often playing Pathfinder, where the Diplomacy or Knowledge or Perception check just goes around the table until someone hits the "DC". I think it makes skills sort of silly and pointless.

Thanks!
