I also got an invitation to join the Hub earlier today. Seems pretty cool, although I've been a member since last October

You basically have the opportunity to do surveys, participate in discussions, the occasional live chat, contribute ideas of your own, etc. I know a few other people from the Hertz FT forum are members there too. Besides holding drawings for gift cards and other incentives, my motivation is that the surveys actually do get counted and given consideration; the live chats even more so (since you are in an online chatroom in real time). Have you seen the Road Trip by Hertz retail store at LAX? IIRC it opened in March -- Hub members played a big role in its creation (I like to think so, anyway ).
