I think karma has its usefulness to keep plurkers engaged long enough to make some friends. After that, seems pretty worthless

do you believe in karma itself, outside of plurk.com ?

I believe in balance, that what you put out to the universe you get back. Some would call that karma I suppose. I guess the answer is yes.

that as long as Plurk karma exists there will be lots of plurkrs who compete for it

I'm not into "karma" per se but believe if you're kind and good to others, others will be the same to you. More reap what you sow than karma

that as long as Plurk and some 3rd-party sites rank peeps according to their Plurk karma, the interest in it will not wane

maybe all semantics...

karma matters! not so sure about on plurk, but off plurk for sure
