Some videos of what happened at the Google IO conference are now online.
Wave really looks like a giant step forward.
Side note about spam prevention in Wave: “In the press conference right after the keynote, a reporter asked about spam prevention. Lars Rasmussen responded that it hasn’t been given much thought yet, since it is a closed developer’s preview for now, but also mentioned that most likely Wave would use a whitelist option, where you’d have to add a friend/coworker before they could send/invite you to Waves.”
Meanwhile, Microsoft just launched a real-time focused version of IE8 using OneRiot components.
