Life in the Fast lane here... The article, "The Search for the Fastest Engine" [fastcompany.com], includes some quotes from John M Lervik, the CEO of Fast. Basically a PR article, it doesn't tell us what the algo is, but there's some material of interest.
No relationship that I can tell between Fast and FastCompany, but the article suggests that a "third generation" search engine like Fast could distinguish between Fast and Fast. ;)
>to busy too check his facts Josk, reading the article makes quite clear it was written pre Google update. Not even Yahoo staying with Google for the time being was clear at the time of writing. So while it's not the most up to date article - in fact it was written for print - it's a nice overview of what's Fast up to. Notice the weight given on corporate search customers - exactly what also is to be found in the Q3 results.
