Oh, I didn't mean that people thanking you were pretending. Only that if they thanked you for one thing, and then you edited your post into another, they hadn't really thanked you for the new post.
And if I were to thank Lewis Carroll for Jabberwocky (as every thinking person should), I would NOT be happy to find that he had turned it into a dissertation advancing his speculation that all of space could be filled with dodecahedra.
