We just signed up for our very own Google Wave account and currently trying it out. We don’t see it replacing email or IM but it’s under development so it can only get better. We see Google Wave as a powerful chat tool when we need to discuss complicated ideas and we need more than text messages to communicate.
We have a few Google Wave invites left so if you are looking for one, please contact us and we’ll be happy to send you an invite. Offer good while supplies last.
