I strongly agree with Venkatesh's main conclusion: "The fundamental social and information flow assumptions of “search” need to be deconstructed and reconstructed for the enterprise. Local/silo search within single sites/assets is fine. Enterprise-wide search in its naive form is a terrible idea."
I agree that flat and dumb enterprise-wide search is broken for the reasons he points out. The principles that make relevance ranked search work well on the public Web fail miserably in the link-poor, (relatively) small scale, cc spammed, siloed and obscurely hidden environment behind the firewall in most companies.
