I have to admit I am fairly worried about this next updated since sj does not have a very good index of my site. Missing backlinks, missing pages, low SERPs etc etc etc.
But when you look at it sj is not the index. It is an index at some point doing something that google really doesn't even want you/us to know about.
Average web surfers don't go to sj. We do to check on what _might_ come down the pipe. In the past it seemed to stand true. Though I do remember directory-sj being months old for quit awhile. Maybe they are just playin' with something new ;) and these don't reflect the new deep crawl (and that's what I'm going to keep telling myself).
