Mine said "hate IE6?". In any case I think it would have been both funny and effective if it led to their products page, something like here is how we will can take your pain away..Redirecting to twitter? I didn't like it.

Agreed. If they show me something awesome, that might give me a reason to send out a tweet. As it stands, I just closed the window.

Pretty scummy, more like.

I think "scummy" is a bit of an overstatement. I would have preferred it if there was a message first explaining how CSS Hat helps you stop using Flash (I'm assuming that was the intent). I'd be more likely to tweet in that case.

It looks like just a joke to me, I imagine it came from 'How do we get all these web developers to click on this link and maybe tweet'
