What a useful thread! We're all very happy for you and I would like to personally thank you on behalf of the whole DP community for sharing this wonderful information with all of us. (notice the irony?)
I'm not telling you what Google Wave is but .. Google is an Internet phenomenon that let's you search for almost anything published in the web - and it's incredibly simple to use! You simply go to http://www.google.com/, enter the phrase that interests you "such as Google Wave", press the "Search" button and voila! - in many cases the very first link displayed answers your question. Amazing, isn't it.
I didn't get accepted to Google Wave. I come back everyday to Google, but it never shows me any affection.
For those (rather ignorant, I'd say) people saying that Google Wave is rubbish, just another collaboration tool etc. I stronly suggest to watch the (yeah, pretty long) video at http://wave.google.com/help/wave/about.html#video and speak up AFTER they actually know what Google Wave is all about.
So how much you guys earn from Google Wave??? I have 2 Google Wave accounts, it didn't change my life yet... Those people who are very much happy about getting the wave, please give me some tips. [To some people: It is an ironical post]
