Found this wordpress blog by J. Douglas Macready: http://therelativeabsolute.wordpress.com/
Looks like an intelligent and thoughtful take on Stiegler’s work.
The wikipedia entries on Stiegler, and on Technics and Time 1 were done by Dan Ross. The TT1 entry is a very useful summary.
Ars Industrialis is the organisation Stiegler co-founded. Its website has numerous texts and recordings of Stiegler, including quite a few in English translation (I helped out with some of these :-): http://www.arsindustrialis.org
