At first glance, appear.in looks a lot like GoToMeeting. That's because both of them use the fledgling open-source standard called WebRTC (real time communication) to set up and connect users for video conferencing in modern browsers (Chrome, Firefox, and Opera, specifically). There are a whole slew of companies trying it, with names like Talky, imo, and Gruveo—there's even a Web RTC feature built into the Firefox browser. Appear.in outdoes them all. It has mobile apps, allows up to eight conference attendees, screen sharing, claims on customizable "rooms," and even just simple chat tools. You can even stick an appear.in room on your website.
Freeflys: Another strong contender in the freebies space, Freeflys has appeared on NBC’s Today Show, The Doctors, Fox News and a handful of other media outlets. Similar to most of these sites, Freeflys utilizes email alerts to tell users about free-sample offers as they happen. The site also allows you to search for a specific product with the handy search bar.
