What I'm about to say may already be all over the Internet. It's always dangerous to comment before searching, but I'm going to say it anyway.
A dear reader asked why I even cared about Chrome. Yet another browser. He said, "We already have Mozilla, and as you have said a zillion times, 'Open beats closed' so why would you think Google would be able to make something better?" Good question. And the bigger question, why would Google even bother?
The answer-- Chrome has almost nothing to do with creating a better Web experience. It is, however, completely about the future of the Internet which will be experienced as a virtual world. It's about a richer and more immersive user experience.
Firefox and the other browsers were built for a different day. For the Internet of the last decade. As simple as we think the browser is it's not simple enough. The current choices are bloated and way too complicated. They have features that the vast majority of people don't use and will never use. Think Word as compared to Google Docs.
Chrome, and by extension Lively, are about the future. Sure they may suck right now. I wouldn't know, as they are Windows only and I haven't used them. I have read enough about Lively, however, to know that most people consider it a joke. That's today. Many revolutionary things have been the subject of derision when first released. Have no doubt, in five years they won't suck and most of us will be using them. Just like we use the Web and Firefox today.
UPDATE: So it is being reported that Lively does not run on Chrome. Funny. I'm telling you, the whole reason we even have a Chrome has everything to do with Lively.
