I've seen today several Adsense Ads with titles in cursive. Maybe is it a Google's attempt to unblend ads ?
I noticed that a while back. It might not be an attempt to unblend ads but to make visitors less ad blind. It could be that they're more likely to notice ads if the appearance of them change from time to time...
I had that as well. It happened when I had just inserted some new adsense. Only did it once and not seen it again. I think it looks ok personally.
You're right. This is that older thread: http://forums.digitalpoint.com/showthread.php?t=253645 But there isn't an example picture
I posted a thread earlier than that on the 22nd with a picture included : http://forums.digitalpoint.com/showthread.php?t=250313
