[darkroom]

Hi guys,
Currently, sj and fi shows different results. First came sj and then fi...

Lets discuss the differences and similarities.

Similarities
1. Both are based on the new algo.
2. Both are kind of immatured results . i.e spam filters need to be applied, more sites still needs to be added.

Differences.
1. fi shows more sites than sj. Proof - The increase in the # of competitors sites for a specific keyword.
I guess this is the only diff.

However, the backlinks for my site have stayed the same. I do see a very slight difference in the rankings from both sj and fi.

Ny other takes?
