 Framing other sites has always seemed scummy to me.  Am I off-base?
inerte: 1 - It doesn't hurt SEO. Sure, a directly link would be better, but a framed one is better than nothing. If it creates duplicate content problems, it's for the framer, not the framed.2 - No. Why do you think it might do?3 - No, I hate them too :) Except isitfunnytoday.com, because, you see... that's the problem. Sometimes you can clearly see value being added by the framer. But these are rare, most framers do it to stick the users, log activity or show ads.
