if i want to comment i make sure to read all the comments in a topic ... starting on page 1 ... no matter how long it is.
one should always make sure to get thoroughly caught up on a conversation in progress before jumping in.
to do otherwise results in constant repetition of points made, dragging up issues already settled, and creating confusion.
it's also like saying out loud that nothing anybody else has already said is worth the time it takes to read it and that only our own thoughts and words matter.
