This has been a thought provoking experiment. As of this writing, the reciprocity service at getwatchers.deviantart.com/
has sent 403 new views my way recently as a result of the: votes, comments, favourites and watches I've left behind. The idea of the service is neat: give and get.
They let you know if anyone has given you a vote of 6/10 or higher. You also know if you've been given a comment, favourite or watch normally through regular channels. My success rate (as in 6/10 or higher) is 4...out of 403. I have a 1% success rate. That's an eye opening number to see.
Most of my work is about loneliness, so I guess a 1% success rate would be fitting. Food for thought.
