As it turns out, there are already a couple of sites similar to zoom.it [1]. However, it should be interesting to see if zoom.it gains substantial traction, and how. I suspect that the fact it's Microsoft releasing something lightweight and useful will make this an interesting news story. This is seeming to be confirmed by Twitter showing a steady stream of links to it, and its gaining a lot of buzz on social media sites.<p>But, we'll see. It's possible that there just isn't enough demand for this type of thing, yet.<p>[1] <a href="http://www.moreofit.com/similar-to/zoom.it" rel="nofollow">http://www.moreofit.com/similar-to/zoom.it</a>
