I assumed he meant anonymously. Jobvent looks like more-or-less the same basic idea. One issue with translating this idea to startups is that if it's a small enough startup, they might be able to tell who you are. You might be the only person who's ever quit that startup, or there might be few enough that they can tell anyway. This could cause issues where companies threaten to give bad recommendations to future employers if people use the site, or something.
