I have been playing around with a wordpress blog because I like to keep my money site blog more professional and very on topic. So I started searching around similar tags on wordpress to comment on posts, I found a linkwheel, more likely a pyramid that eventually (~4-5 tiers?) leads to knol as the article that has 2 out of 2 links going to the M$. Now that knol is going away shortly, does this mean all of that backlinking is wasted? Or does the chain mean this looks more natural? I am going to try building a linkwheel with non spun content and I would feel pretty awful if I spent all of that time to have one of the sites go away and all of that time be wasted. Any thoughts? Or is this just a big waste of time to do this?
