you're more engaged. hence your karma is higher. By default i dont want to follow "i just got coffee" posts. nothing interesting there.

not to say i'm not interested in your coffee addiction. I am. But not everyones coffee addiction. :-p

yea. maybe i'm just conflicted in how i want to use Plurk.

these people find it to be their JOB to aggregate "interesting" things

like Doingle Doingle, but just interesting stuff, not all information
