I usually do not. I confess that I have somewhat of a trouble to concentrate (confused?) especially if it is a long post as well but most of the time I don't see this as a bad thing except it is somewhat disrespectful towards the original poster. I usually do not read the rest of the posts as well before responding. I usually just read the title and then respond. I usually notice / feel that I have (my) the post that in my mind before I even enter the thread. I usually post first (or I just skim quickly over the post) and then go read after. It is a little backwards I admit but I usually notice that I post things that have already been posted without looking at the rest of the posts. Now, other INFPs, how about yourself?
