You mention backlinks for seo. I would expect most submission based websites use nofollow links thus providing no link juice. Can you comment on how many of these 100 sites do or do not use nofollow links?
Cool! I've thought of doing this as well.<p>One idea I've had is to stagger the post based on how the site's traffic gradually drops.<p>If you have ever seen the end of the movie The Core, they use the energy of the bombs and create a chain reaction to keep the earths core moving. I'm sure the science is sound...<p>In doing this you could keep the project moving over a longer period of time rather than a big bang which might fizzle out.
Interesting but without sharing more about the websites where you publish or the number of subscribers you have to your list I wonder how people can trust you.
