So maybe we should do this like ESPN does the play of the day. Take the tool of the day for yesterday, this particular professor, and he wins the tool of the day. The next time someone posts a TOTD we compare the two and if the professor is still the winner he then continues his reign as the TOTD.
This way, the professor never goes away, until there is an enormous TOTD to knock him off his high perch. Because I kind of don't want him to just get lost in the mix.
