Are pseudogenes transcribed?

See:

How the Junk DNA Hypothesis has Changed by Richard Sternberg.

If pseudogenes are transcribed, then this is yet another gaffe by Ken Miller and Richard Dawkins.

Actually, the gaffe is Sternberg's.  As explained here.  The brief bottom line - there is a lot of background transcription of junk DNA, and the products of this transcription are broken down almost immediately.  Sternberg is wrong to claim, as he does

...if one considers functional DNA to be equivalent to transcription units ..

that all transcribed DNA is functional.  

I'd post this on TT, but I was silently disinvited long ago.
