Seems the Linkie-Winkie crawler was here again yesterday or early this morning. Still haven’t figured out what the time half of the equation is. Aside from that, it’s really a fairly simple concept.
If you get the timing right, and post on Linkie-Winkie, then Linkie-Winkie will add a link on LinkieWinkie.com back to your post. Side effects are that you then share in the Linkie-Winkie traffic.
Unfortunately, based on the graph on their site, there isn’t much traffic to share. Still would be interesting to see what happens.
