Robert Scoble não gostou muito do Google Wave – Artigo em inglês. Nas palavras dele: "(…) But this service is way overhyped and as people start to use it they will realize it brings the worst of email and IM together: unproductivity. See, the first thing you notice is that you can see people chatting live in Google Wave. That’s really cool if you are working on something together, like a spreadsheet or a Word document. But it’s a productivity sink if you are trying to just communicate with other people.
