i am using it to track succesful/unsuccesful hits to our search engine.
if i see a spike in unsuccessful hits i know to investigate.
also since caching search results was important (we get many searches
per second) but difficult (many things can change that would invalidate
a certain set of results), i fudged it by keying on the md5 of the sql
query used. i used memcache to measure the effectiveness of this
approach to memcache by logging the # of searches and the # that could
be served by memcached results. turned out to be something like a 66%
hit rate, which was pretty impressive for me considering that we did
absolutely no work on making it cache-able.
