I'm a very happy SENuke Customer, but after using it for the past few months I'm starting to see very little impact on the sites I manage. I believe the reason for this is that I have exhausted the SENuke database of sites which it posts to. I do not believe there is any value to be had from multiple links from the same domain.... so running an SENuke blast 10 times is going to results in 10 links on blogger.com, 10 on Wordpress.com etc etc, where you only actually get link-juice from ONE of those links. If SENuke had an ever expanding list of sites it posted to, that would solve the problem, but this does not seem to be the case. The only possible long-term use I can see is to blast article sites, rather than blasting the money site. I'd love to hear other peoples thoughts and what you are actually doing.
