I have had that happen a couple times myself

It's always something... I'm sure it's just a hiccup from time to time.

True... But it seams like the same people are in the ones that won't go away for me?

I've never plurked by accident yet....

could be that someone commented on it as you were marking all read - keeps happening to me

adamdesautels I've seen the same thing - always the same people or post.

oh that I do GeekMommy

tojosan never plurked, but Tweeted - that's a different story.

GeekMommy Slight possibility, but it's usually the same post. Over & over & over & over.
