We posted a sample hazard report map using SeeClickFix several months ago and now we have put it online on the BCGP website: http://www.bicyclecoalition.org/report/seeclickfix
It is also available as an RSS feed.
Simply click on the map to report a problem, make sure you include the either bike or bicycle in the description so we can track the problem.
In Philadelphia Philly 311 monitors SeeClickFix entries, they also produce a service request number which allows to you track your complaint on their website.
Outside the City you can designate yourself or a decision maker in your community such as a Bicycle Advisory Committee contact or Public Works Manager as a "watch area fixer". They will receive email alerts of hazards in their watch area, a feature that they can easily disable if they choose.
