Heyzap is a bet on the "deportalization" of casual games on the web. I wrote a post a while back about the deportalization of the web. And since then, we've only seen this trend grow. And we think there is no reason why game playing on the web will be any different than any other behavior on the web.
My partner Albert wrote a post on the Union Square Ventures blog about this investment and the reasons we made it. I hope you'll take the time to click on over and read it and let us know what you think.
