While announcing a product with a huge event is one way to go about things, sometimes you just want to release something in a small fashion. Quietly. That's exactly what Google Labs has done with Google Shared Spaces. It's open right now in a very non-public fashion, and it's meant to showcase the technology that powered Wave, but in a far more creative way.
And while Google Wave may have not survived, it's good to see that the technology, which promotes real-time collaboration, is still around. If Google Shared Spaces can take off, that could probably be considered a notch in the "win" column for Google, even if it took a bit longer to achieve. As for a date regarding a public opening, Google didn't say. So it looks like we'll have to wait a bit longer before we can all experience what Shared Spaces has to offer.
