Another "No" vote from me! I am very erratic at keeping in touch with people. Like other INFJs have mentioned, I am very future focussed, so find it hard to even remember acquaintance's names after a certain amount of time.
I do have some good friends with whom I stay in regular contact thanks to email (I also dislike long phone conversations, which drain me so much I begin to tune out completely.
It is one of the many things I berate myself for, as my "Ideal Self" would be wonderful at staying in touch with people. Maybe our problem is caused by a clash between the conflicting goals of Ni and Fe? Since Ni is dominant it usually wins, but our Fe has sufficient input to make us feel guilty about ignoring people.
