Search terms in your referrer logs are a funny thing. Sometimes I think that the search engines are ahead of me, indexing things that I will say in the future. For example, someone found my site by looking for the terms: behaviourally anchored rating scale. While this term was nowhere to be found on my site earlier today, when the poor, confused searcher ended up here it is on my site now. See what I mean? It's as if Alta Vista can predict the future. Perhaps this search really came from tomorrow, and my logs are reading the future. In any case, all of you folks who are ending up here looking for something perverse thanks to this quoted post from the past will be disappointed. However, it may show up here in the future. Now.
