I came across this post at third hand but the quote is great:
…the enduring elephant in the room is what I like to call Culture 2.0. That is, those at all levels of government who find solace in risk aversion, are tenaciously resistant to change or are simply unable to acknowledge the benefits of Gov 2.0 over the risks. In fact, let me suggest that Culture 2.0 could be the single biggest threat to the penetration of Gov 2.0 in Australia if not addressed.
The route to this was a tweet from R “Ray” Wang @rwang0, to a blog post by John F. Moore in Government in the Lab, to the original by Rob Crispe.
