The unprecedented precision and cadence of Kepler photometry has already resulted in a wealth of new candidate planetary systems. However, it has also given us a window into a previously unseen stellar variability regime that tests the ability of software algorithms to identify transits in the astrophysical 'noise'. Using the publicly released Kepler data, we built the PlanetHunters.org Zooniverse web site to take advantage of the natural pattern recognition capabilities of large numbers of citizen scientists. Individuals classify lightcurve variability and mark transits using simple interactive plots on the web site. After one month in operation using only the first 32 days of data, more than 1.1 million light curves were classified and users identified 90 strong potential candidates. Here we present information about 5 unique planet candidates which have undergone extensive testing for false positives and have not been subsequently published by the Kepler team. We have also taken Keck HIRES spectra of the stellar hosts and so provide precise planetary radii and periods as well as improved stellar properties.
