Amateur Radio information on modern social networking.

I'm slowly starting to get some of the appeal of Reddit.    At first I was drawn there by /r/rtlsdr, as there didn't seem to be much info elsewhere.   There is a bit of a digital divide, for on-line sources many hams go to QRZ.com with it's 1990's design and god awful ads flashing all over the page.  Try as you might, some of the old guys can't remember to try anything but QRZ.com. The other big source of info is Yahoo groups which are starting to show their age, but have been made much less useful due to Yahoo trying to figure out how to get more page views.

So two useful places to get answers to amateur radio related info:

1. Reddit: /r/amateurradio  [http://www.reddit.com/r/amateurradio/]
2. StackExchange: ham.stackexchange.com [http://ham.stackexchange.com/]
