It appears as if DL6KAC of ham-blog.de has come up with an interesting idea. He has created HAMigg, which is a social bookmarking site like digg.com but dedicated to ham radio! I think this could be very successful, as long as people get the word out. The name of the site doesn't exactly roll off the tongue, but gets the purpose across to those familiar with its inspiration. I'll be watching the site, and likely submitting to it as well.
