Oh, a programming note here ... Don Imus is back on the radio at WABC, New York. That's 770 on the AM dial in the New York area. Or, listen online -- click here. I'm certainly not suggesting anyone excuse his on-air remarks that got him in so much trouble, but I will point out that he and his wife have been tremendous advocates of the autism community. Imus was talking about the ins and outs of autism issues, including vaccines and thimerosal, before it hit the mainstream media. Like I said - just pointing his return out.
