The Stack Exchange Network frowns on greetings and taglines in posts. There were mixed reactions to this before we moved to the network. Should MathOverflow tolerate greetings or not? Is it appropriate to edit greetings out along with another edit?
I would prefer the site without greetings and taglines. I would especially like to remove signatures with inserted "middle names", since I find them distracting and annoying.
MathOverflow states that the behavior expected of users is: "do not use signature, taglines, or greetings" (https://mathoverflow.net/help/behavior). This is StackExchange general policy -- let's respect it.
