Its a harmless bit of gamification that I like. Watching a number slowly climb as I interact and make quality post helps keep me motivated. My ego isn't tied to internet points. Its not earth shattering to me to lose them, just a bit wierd. Please get off your high horse, I know this isn't reddit.
Mine dropped from like 35 to 2 for most of yesterday but bounced back up to where it should be today. Looks like it was a temporary glitch in the system.
