I'm interested in the topic and am engaging in discussion on it in two threads at once.
Just like you.
No there is a difference between having a conversation on two different threads and you jumping in out of the blue and making three posts in less than two minutes on one thread and then 60 seconds later already having your first of two instant posts up on another thread when we were not even conversing.
That is called stalking, it is not just coming across a couple of interesting threads on the same subject.
