Yahoo! seems to be the only engine celebrating Cinco De Mayo with their logo today (though it's still early). Sadly, if you click on that logo, you get this page on the "buzz log" for the celebration. Problem is... Yahoo! allows unchecked comments here and people have been using it as a political forum regarding recent immigration issues between the US and Mexico.

Yahoo! Cinco De Mayo Logo

There are some particularly ugly and vile comments not worthy of repeating, but the big issue is how this affects Yahoo!'s audience that happens to click-through. I know that a lot of folks use Yahoo!'s search engine because it's been their default home page since they first got an Internet connection (even I'm in that boat, having switched back to Yahoo! after various trials with personalized homepages and RSS feeds).

If I were them, I'd make sure that nothing would create an incentive for my users to switch their homepage - this debate today in the Cinco de Mayo comments hits their demographics hard and projects exactly the wrong kind of image. Let's hope someone notices soon before more of Yahoo!'s market share goes over to Google.

UPDATE: Apparently, someone from Yahoo! was paying attention, as the comments have now been removed from view. Sorry I didn't screenshot it, but then again, there was really nothing worth preserving in there. Kudos to Yahoo!
