I don't think many people understand why Facebook is so popular. I don't think it's status updates or micro-blogging. Facebook simplifies the internet for people who don't want to be using the internet. A one stop shop for people who don't trust the rest of the web or installing software. Photo-sharing, IM, mail messaging, games. It's all there with a simple interface. Even my mum can use it.<p>Google has a huge range of great tools, all available under a single login, but their presentation is a total mess.<p>I'd love an opportunity to spend a few months building a better "Google Portal".<p>Oh, and I don't think anything they make will just grow virally. If they want it, the'll have to buy it. They should spend a bucket-load advertising it in mainstream media.
