Thanks for the unnecessary quotes link. However, that site doesn't seem to be taking into account emphasis quotes, which are an entirely legitimate aspect of English writing. For circumstances in which emphasis cannot be added with italics (for example, marquees), this is a common and, I think, acceptable practice. I think, if possible, we should make use of a richer vocabulary first, and if that doesn't work, and emphasis quotes would not send the wrong message (e.g. that child is "special"), it's alright.
What I love about language is that it's always changing. I don't know if I'd call it progress, but English is a living language.
Agreed on emphasis quotes, but they are still much overused, especially in advertising, informal notices, etc., where other devices could be used.
