What to do with shortlisted producted info?

I have accumulated loads of data about what my visitors like

I introduced a shortlist script to some of my sites a few months back and later started saving this info to a database along with session IDs. Now I'm wondering what to do with it!

Any suggestions - I thought I could have users favourites on the homepage. Is this likely to increase revenue?!

Thanks,
Chris

It would hurt to a have a featured product based on peoples likes, would it?

Put it on the front page and see what happens.
