I will start using this immediately whenever I get a boiler plate boring request to connect from someone I do not know:
Dear connection requester whom I do not know,
I could not have said the attached link better, although I have been preaching on this topic for years. I am sending this to you, and I want you to know that LinkedIn wrote it.
Since you did not see fit to tell me where we met, whom we know in common, and/or how we can help each other, I suggest you learn from the link below to save yourself embarassment and further declined invitations.

Blog readers, feel free to use this too, as we work together to eradicate this laziness.
