I agree with Martinibuster. If we're blocking these crawls to improve user experience, but then being asked to unblock them for Google's benefit, Google is sending really mixed messages. It's kind of, "Forget the algo, just build your site for visitors - by which we mean, build your site the way WE would build it if it was ours."
Given what Google did to Yelp (http://techcrunch.com/2010/08/26/google-places-yelp-stoppelman-awkward/), I'm sure not going to trust them to treat my little sites even half that well.
Frankly, I'd sooner just block Google bot entirely.
