Thanks for taking a moment to let me know that my comment is appreciated and that this information makes a difference for you. I find that, like Luke says in The Power of Reinforcement, knowing that a behavior of mine has made a difference and is wanted "increases the probability that the behavior will occur again".
I think LessWrong could really use more positive reinforcement, so I hereby positively reinforce you for showing the humility to positively reinforce.
You're welcome.
P/S/A: There are single sentences which can create life-changing amounts of difference.
