the reading public's response to the recent books and reviews in the media---all that stuff seems to have concerned some people at KITP, who have taken George Johnson in as "journalist in residence" and are having him explain the situation and advise them----there was a fascinating 1 hour talk he gave 20 October which is available as video.
thanks to Peter Woit for flagging it

I would actually recommend downloading it, if you can, rather than streaming, because then you have the Quicktime movie on your desktop (or whatever the appropriate format) and it does bear repeat viewing.
Interesting questions and comments from David Gross, Amanda Peet, and I think maybe Jim Hartle, and several others.
=================
to continue gauging the reading public response, as of Sunday 22 October at 7 AM (after the NYT OP-ED piece by Brian Greene, and several days of seemingly heightened buyer interest in stringy books) the Smolin book was back as #1 physics bestseller.
1. TwP
2. Hawking Briefer
3. Greene Elegant
...
the Greene book at #3 was the highest I have seen it in many weeks.
and the index (average rank of 5 most popular) was 15.8. In my rough estimation, this is comparatively high. A week or so ago it was fluctuating around 20-some IIRC. the generally high interest in string-oriented books is in line, I think, with Greene's Elegant rising to #3 spot.
=============
I suppose it could be that interest in string popularization and also in Smolin and Woit's discussion from a different perspective actually RE-INFORCE each other by stirring up interest! From the point of view of journalism and selling books, it is NOT ZERO SUM. I am not sure about this, certainly, and all I can do is watch the few meager indicators I have, unless someone can suggest some other sources of information.
===================
here is the average rank of the 5 most popular stringy books on the Amazon physics list for the past three days. always sampling at the same time, 4 PM pacific. I think there may have been a spike in sales right after Brian Greene's OP-ED piece (that mathman mentioned above). the op-ed piece did not mention Smolin or Woit and did not give their book titles---rather it discussed issues in general terms. But it made the case for continuing to favor string research and it gave the titles of two of Greene's books "Elegant" and "Fabric".
