How did I get to Link Propagation and "discovery Credit"?
I am subscribed to Fullasagoog who carries John Dowdell's blog. John found the article via Instapundit, who I assume reads Many-to-Many who borrowed the idea from many blog sources. I think I should also add that I am subscribed to Anil Dash's links and can just as easily credit this to him.
Link Propagation and "discovery Credit" has some interesting observations on giving link credit and losing the trail and just like John Dowdell, I find that this looks like an interesting article to read with lots of source links but I am unable to get into it tonight.
