By the way, I just noticed that I have got something like 15 Google Wave invitations left. If you still haven’t tried Wave and need an invite, email me at c [dot] continisio [at] gmail [dot] com
You can even ask me for 3-4 invites together, just send me all the addresses and make sure they are Google accounts.
I found only one practical use for Wave, but I can’t say that it’s a stupid tool. Maybe it will slowly get the attention of people, and indeed it is something to try at least once.
