One thing's for sure: Yahoo! (NASDAQ:YHOO) is a survivor. Once a poster child of the dot-com bubble, it managed to hang on after the sudsy pop. Many of its peers, including AltaVista, Excite, and Lycos, are still around but nowhere near as relevant in today's marketplace.

Naturally, talking Yahoo! -- a Motley Fool Stock Advisor recommendation -- means looking at its success overseas but also some of its shortcomings closer to home. Sure, it was able to chase eBay (NASDAQ:EBAY) out of Japan a few years back, but does it have what it takes stateside to go up against Google (NASDAQ:GOOG)?

Microsoft's (NASDAQ:MSFT) Live and IAC/InterActiveCorp's (NASDAQ:IACI) have recently upgraded their engines and fleshed out their paid-search platforms, so it's not as if Yahoo! can ignore what's happening these days.

This week, Tom Taulli and Chuck Saletta can't see eye to eye when it comes to the investing merits of Yahoo! at this point. Tom is our bull. Chuck is our bear. Where do you stand? That's what this bout is all about.

Duel on!
