I am surprised not a lot of people at HN do this. Disabling predictive service is one of the first things I do after installing chrome on a new machine. Something about sending every keystroke made on the omnibar to Google makes me feel uneasy, it could also be the paranoid in me talking.
So that's why every time I start typing a reddit url, Chrome suggests I visit http://www.reddit.com/r/gone wild (sic, with the space in there).
There are a number of reasons why they really need to rethink this, default it off, or do some better filtering. Didn't impact me personally beyond the confusion but I could imagine that URL and maybe some others coming up in what appears to be someone's unique search or browsing history raising some interesting questions at work and/or at home for some users.
