We might be willing to pay. It might also be possible to marshal a community effort, if it were organized in the right way. Hmm - there might be something to this idea. The trick would be to set it up so that even if it failed, it would be an interesting failure.

You can get intriguing descriptive statistics (n-gram frequencies, time distributions) from even a relatively small labeling effort, well before you have much predictive value. So, in that sense you'll have something interesting in failure.
