Are you sure you didn't get any stumbles? You could have received no traffic and still gotten stumbles from other people I think. It is frustrating to see your articles get lost in that thread; I've been there, showing up quite late, but I actually got a pretty huge traffic spike after posting a few articles in that thread. In any case, I don't know if starting a new thread (if that is what you're trying to do here) is any kind of a solution. This reminds me of starting a new pyramid scheme because the old one can no longer support those at the bottom.
This seems to be representative of the general problem in blogging to day: overcrowdedness and too many late adopters. I read an article today about how there really was no money to be made in the "long tail" of blogging and I had to agree.
