Seems like every couple weeks there is a thread here on Ford Barn, AACA, &c, lamenting the fact that 'young people' aren't interested. Personally, I don't think young folks are dismissive of the content (I'm in my mid-30's and love pre-war autos), but they do tend to struggle with the context (stuffy monthly meetings, newsletters).
In other words, the "message" of vintage automobile restoration (or modification in the case of the HAMB) isn't what young people "don't get"; it's the means of communication. The younger generations have been conditioned by technology to 'think' in terms of dynamic moving pictures, icons, and graphics. They exist in a media-rich world...too many organizations simply aren't speaking their language - the "dialect" of social media is a prime example.
I'm glad to see the changes on the HAMB - I liked it before, but now think that it has a more 'integrated' feel with the additions of Instagram and the cleaner, more icon-focused layout.
