Can you store recommandations 'tags' in a session?

You could optionally store a cookie for 30/60/90 days that has some unique token that references associated tags in the database. That way you have persistence and you can link up user accounts with the token data later if you want increased persistence. Anonymous users will remain anonymous but you will be able to profile them (this is probably similar to what Amazon is doing I'd assume.)
