The way I interpret this is that your tastes are similar to those
of "Sedi 200". This user's latest purchase was a geophysics books.

Discovering so called "serendipitous" items, items that cannot

are very desirable to the consumer is the holy
grail of personalization. As the example above shows it
can go totally gaga.
