I’ve been happy using GoToMeeting, iChat and Skype but this looks like an interesting new option and I appreciate their use of open web standards.
Using only HTML5 and Javascript, the service syncs your browser window with the browsers of viewers whether they’re using IE6, Chrome, an iPhone or almost anything else. Transitions between images are super-fast and the service is a joy to use. It doesn’t include things like markup or native voice support (you’ll have to get on the phone) but for $15 per month, we think it looks like a great deal.
