Interesting piece from Wired on blocking Blogs from Investment Banks. No Longer Safe For Work: Blogs. Not necessarily because it says anything that we don't know about Investment Banks ability to bury their head in the sand, but because of what James Enck has to say about the value of research to his buy-side clients.
The sort of research that I mostly require comes from Blogs. From time-to-time I need hard numbers, but mostly I need smart people to think about how the future, both immediate and medium-term (tomorrow to 5 years). People such as James do a great job of doing that.
