Anyone can now use Google Wave. No invitation needed!

Today, Google is announcing that Wave will be open to everyone. This includes not only consumers with Google accounts, but also Google Apps customers. The project is now a part of Google Labs, where it will remain as work continues on it. But much work has already been done — if you haven’t tried it in the past few months, now is probably a good time to revisit it, as is it much more stable and faster than it was in the past. And it’s full of some new features that should make it more obvious what it can be useful for.
