curious... does plurk karma have anything to do with the way one's posts are viewed in the timeline? For example do people with lower karma not get listed as much?
No. Plurk treats karma like a drug dealer. You get a lot really fast until they have sucked you in to the karma game, then it's slow as hell and gets slower and slower and slower until it goes up a tenth of a percent and drops quickly.
From what I remember, plurking throughout the day, but not in bursts, will up your karma. Like a plurk every three hours is optimal, but five plurks in a row is bad for karma. Plurks with lots of responses, likes, replurks are good. I swear some people would post drama plurks for karma.
Not plurking at all is bad for karma, it drops. hmm, I don't remember anything more. Oh, you can freeze while you go on vacation so you don't lose 20 points of karma while you're away.
