Hey everyone....long time no talk. Hope the past couple years have been treating everyone well! I'm doing some research at work for an upcoming project, and I'd like to feel everyone out about current social networking sites aimed at auto enthusiasts. If you guys don't mind, this would help me out tremendously if I could get some responses to these questions.

1) Do you currently use social networking for car related stuff (events, car profiles, etc)?

2) Which ones do you use?

3) If you don't currently use one, why? Are the interfaces clunky and hard to use? Lack of features? Just don't care? Are they too broad when it comes to types of vehicles and members that are on the site (or is that a good thing)?
Anything you can tell me here would be great

4) If the issues from #3 were addressed, would you use one to supplement HAN and any others boards you may be a member of?

5) If you do currently use one, what features do you use the most? Messaging, events, photo hosting, video hosting, groups, etc?

Anything else you guys want to add would be appreciated as well.
