It is obvious that only robots leave any sort of comments, so far I have read only one that may stay because it mentioned something from the site (advanced bot).
I leave comments manually, and many stay because I use some of their keywords. Concrete Galoshes Day is a good one to use, CCL or crazycl or even CrazyCousinLance would do nicely, especially if you want some link love. Later
