Dear Google, who I am supposed to use google wave with? 17 years ago
Okay, I think they did an amazing job. Maybe it's because I got ~10 people that I can speak with. 5 of those I take notes with in school I.e. collaborate. The other 5 just random friends and relatives who showed an interest. I speak with them occasionally. Along with that I talk with many people on the public waves.
Yes, life is though when you got no friends to talk to, but I would recommend you to search for "with:public" to get some people to talk to.
It's not Google's fault you got no friends.
