There was an interesting chat session held last night on Twitter. You can find it at http://search.twitter.com/search?q=carchat
Unfortunately, as of this posting, you have to go about 30 pages deep to find the relevant stuff from last night that is from the Nissan rep. Perhaps there is a quicker way to get there, but I am new to Twitter as of last night. I created an account just for this event. For those of you who follow the Leaf closely, there was not a lot of new information, but it might be worth checking out.
