Do you think you've given or received more lurve?

Maybe the mods have these stats – I’m pretty sure they can at least see who gives each other lurve. I honestly have no idea for myself, but I’d estimate that I give about as much lurve as I get. How do you determine when to give someone lurve? I always do so if I find an answer particularly insightful, humorous, witty, or in line with my perspective. Are there certain users you’d never give lurve, no matter how great their response was? Do you get so competitive as to neglect to give someone lurve who deserves it because they have a higher score? Or do you act objectively, doling out lurve when its deserved?
