I'm surprised there is so little activity on this site. I'd like to see more - probably others would, too. (By the way, my thanks go out to the techies who keep this forum system operating.)
Why I'm surprised at the low activity is that there have been all the Farm Hack events. Surely a promising or viable design or method is occasionally coming out of these.
There are threads started here (often with a pic or two) and orphaned. No follow-up, even when interest has been shown via a reply to the topic.
Farm Hack forums have got off to a great start in life, but in my opinion the whole project needs feeding.
