You're welcome! I don't think it's something new by me, but if nobody beats me to it and I'm in the right mood I like trying to get in the head of people and saying "Hey, here's a thing they might not have realized, let's help."
Admittedly, I'm usually more brash and I often come off as judgemental, but I know that I'm speaking to people who don't know me and I sometimes manage to remember to avoid the "you're wrong, do this instead!" tone. ;)
