Free database of Google word frequencies?

Question

On the Stackoverflow podcast this week, Jeff mentioned that in 2004 he wrote a script which queried Google with 110,000 English words and collected a database containing the number of hits for each word. They use this on Stackoverflow e.g. for the "Related" list on the right-hand side of each question page.

Since creating one of these today with a similar script would be difficult (as Joel mentioned, "at 30,000 words you get a knock at your door"), I was wondering if anyone knows of a more up-to-date, free database of Google word frequencies (e.g. for IT words which have surely changed since then such as jquery, ruby, azure, etc.).

Answer 1

A quick Google search(!) turns up a few hits. This link looks promising:

But it's not targeted at IT words.
