A combination of Google+ Hangouts, Skype and YouTube, OnTheAir is a new site that wants to create communities of like-minded individuals via live video conversations. Launched into private beta, anyone can create a live video chat on the site. The idea is to make interactive live video a seamless experience that helps people cultivate groups based on their interests. Here’s how it works: Say you want to host a channel about blogging, you can schedule live conversations at any time and moderate who speaks. If you connect the tool to Facebook and Twitter, the site automatically shares the time of the chat to Facebook friends and Twitter followers. Another cool feature — there’s no limit to how many people can be in the queue to ask questions. To help ensure the quality of the site, the designers implemented “aggressive checks,” including a requirement that anyone who signs up must have at least 25 Facebook friends to ensure they’re a real person and not a spambot. Right now, the site is free to everyone and, unlike Google+ Hangouts, there’s no plug-in requirement (Hangouts requires a 13.6MB install). As the team tests the site with new users, they plan to fix any quirks and add additional features such as the ability to record and save live chats.
