A lot of people are beginning to play with Google Wave - even some of us within the car dealer social network community.
Many are confused as to what it is, what it does and how it can help you.
In a nutshell, it can be whatever you need: A clunky chat-room, a private workspace to share rich content or something even more engaging by using installable gadgets such as napkin, brainstorming and HTML...
I like the simple features over other sites like Basecamp.
A Google Wave iPhone app is also available for $1.99 - it is't an official Google app, but it looks and feels like the full application - just smaller. It seems to run slow - but does allow the same basic functionality.
Here's The Complete Guide to Google Wave to help with pretty much anything you may need to know. Hope it helps...
BTW - I'm email@example.com
How have you used it?
