EDIT: I'm changing this to a general Google thread
So today
Google Wave goes into closed beta/ "limited preview."
In short (as I understand it) it's a bit like a more buff'ed up IM service but crossed with blogs. So you can embed replies directly in response/under the original comment instead of belatedly replying to something someone said 10 lines ago. You can also embed pictures, maps, documents, videos etc which will probably not only complement Youtube/Google Docs/Google Maps but it will probably also be really useful in context of a group project.
But I really doubt I'll be checking it out anytime soon (it took me like a year to get a gmail account

)
Anyone get an invite? Or if you didn't, anyone else excited? Or any other comments about Google & their products?
