>Actually I hadn’t heard about Google Sites until I read this post: Google Sites vs SharePoint. Pretty interesting, I can see that Google Sites has some way to go but for the majority of home consumers it sounds like it has a lot of functionality that is useful.
I don’t think its a competitor for SharePoint in anyway (yet!) just because of all the enterprise features that are available with the enterprise search (searching content types/line of business apps), document management, workflow etc…

However it does sound like it will start pushing user interface design, which is where SharePoint is still lacking and is often the first port of call for customers. So that’s not a bad thing at all, it is healthy to have this competition – it’ll just make SharePoint stronger!
