I still don't understand why we need an "instant" world. Is a week too long to wait....is 3 months too long to wait?
A week, no. 3 months yeah. 6 months, definitely. If you actually read some of the points, your perspective might change. For instance, THE END USER GETS TO SEE DELETED CRAP FOR 5 MONTHS NOW. This is why updating SCORING can be useful as an example.

Why would anyone here possibly care? This has nothing to do with the topic. Go discuss your brilliant SEO strategies somewhere else. Maybe you can start a thread about why using really old data is fine, but this was intended to be a discussion in which we could talk about reasons WHY this is occuring.
Yahoo's problem involves something that isn't a deliberate part of the algorithm - a failure to include all of the data it has gathered until many months later.
