One of my better picks as a member of the Rule Breakers analyst team was when I recommended The Knot (NASDAQ:KNOT) a year ago. The shares were fetching just $11.81 apiece at the time, and the prospects looked bright for the company.

What is there not to love about a company that is the category killer in online wedding planning? You have vulnerable brides-to-be, willing to fork over tons of money in pursuit of the perfect ceremony.

It's never as easy as that, though. Companies like The Knot and Bankrate (NASDAQ:RATE) have been Wall Street winners by providing industry-specific leads, but others like Autobytel (NASDAQ:ABTL) in auto retailing, InsWeb (NASDAQ:INSW) in insurance, and HouseValues (NASDAQ:SOLD) in realty have struggled.

Tack on a few ordinary quarterly performances out of The Knot lately and I can respect the valuation concerns that Chuck Saletta has as this week's bear. No, I'm not stepping in as the bull this week. I'll leave that up to my buddy Tim Beyers.

So does The Knot belong on your bridal registry? That's what this week's Duel is all about. 

Duel on!
