You don’t let me leave a comment without registering, so I’m not going to. Trackbacks are so much prettier, no?

Anyway, you tell your publishers:

Don’t manipulate our ad code. We’re flexible and already offer plenty of choices.

I have to say that’s completely nonsensical. I never used your ad code when I ran YPN ads. It was just too limiting and broken. It didn’t validate because you didn’t declare the script mime type as “text/javascript.” So, I added that to the ads myself. Then, your color picker just sucked, so I hand coded the rest of my colors. If you’ve got a problem with that, I would recommend that all your publishers drop you on moral principle. Otherwise, you might want to clarify the above statement.

What you probably meant to say is something like:

You must include the ad code from our servers, but you can customize the rest of the javascript on your site.

Wouldn’t a statement like that make more sense? It might make publishers more comfortable, too.
