My report of the visit of Omar, Mohammed, and Spirit of America to Silicon Valley is up at Winds of Change. See also Dan Gillmor's report, Silicon Valley Redneck, and Renee Blodgett.
For those interested in a blow-by-blow of the brothers' tour, Kesher Talk has an ITM and SoA linky fest. (And BTW, Judith, I'm Tim Oren, not Tom. Tom is my better looking and taller kid brother.)
