How did google crawl this? Was the pdf link just taken down?

  We can assume so.

  If you search for site:wolframalpha.com , you'll see that Google even crawled some search results. I guess when it was briefly opened earlier in the week, Google had a look. Also, I got one of the TC invites to try W|A a couple hours before the main launch. It is much less useful than you'd expect. No data on: crime rates, test scores, alcohol content (though it does tell you the LD50 of alcohol), etc. Fun stuff: side-by-side comparisons. Compare Apple and IBM, or Harvard and University of Phoenix. Also, for some of the stocks it shows a "simulated log-normal random walks based on historical parameters" -- a couple charts of ways the stock could theoretically perform in the future. Not too useful, but fun.

      Yeah, they had to send a follow-up email. It looks like the beta was kind of last-minute; my email from the Wolfram folks misspelled "Wolfram" and "Password" -- and mixed up my password and my username. But they caught the relevant mistakes pretty fast.
