First, you don't need to convince me that the eminence model is lacking and that Silverman's contributions to the field have been numerous and worthwhile.

As for links--I'll list some below.

Indigo children:

Also, pages 112-114 of the book Hothouse Kids by Alissa Quart

Vision therapy:

This may have been discussed on the TAGPDQ list. The contention was that the GDC suggested vision therapy to a disproportionate number of clients. The people discussing it were skeptical of VT and thought that the GDC was being fringe-y for recommending it. Disclaimer: They suggested it for my son, and they were right--he needed it.

SB L-M:

The controversy here was over the use of an extremely outdated instrument. Again, I think most of what I know about this came from the TAGPDQ list. It's not clear to me that the GDC even uses the L-M any more.

Again, pages 112-114 of the book Hothouse Kids by Alissa Quart

There is also this New Yorker article, which discusses some of these issues: http://positivedisintegration.com/newyorker.pdf
