Facebook Event Gender Count
No more unexpected sausage fests or clam bakes! This Chrome extension tells you how much bros and hoes are attending a Facebook event. Open Chrome Web Store
To experiment a bit with the Facebook Graph API and Google Chrome Apps we put together a simple extension for Chrome that tells you how much females and males are attending an event. The extra event information integrates nicely with the original Facebook UI.
N.B. The plugin will error if you aren't using Facebook over HTTPS, but that won't be a problem, right? Also, sometimes the plugin will just stop working. Refreshing the page will kick it back in action.
