Rewinding Twitter

Google announced today that it is giving the ability for us to go back in time and see Twitter trends. One challenge that remains (at least as far as I could make out) is that these trend indices are not downloadable yet. Perhaps, some old fashioned eyballing and coding into low, medium, high type categorical variable might be a crude but effective way to capture this information. It should be helpful for those of you wondering what the buzz was for a movie three months ago...Let me know.
