Dom,
That is a great insight and I am in agreement that it seems the age of links (and domains) could have something to do with there overall strength. Why not factor that consideration into the algorithms? With online casinos being a competitive market as it is, imagine all of the linking that just comes and goes even on a daily basis. This makes your idea even more plausible. I will think twice before “i really don’t care” if a lesser site decided to delete my article. Seomoz say no, but there is debate and I am leaning to ….why not?
