Today is Memorial Day, and as a result, the Ask.com search engine has recognized the holiday. There's no indication that Google and Yahoo have done anything in their logos to commemorate the day, which we've covered in the past. It appears that they will not be showing any commemorative logos, similar to last year and the year before.
The Ask.com site has a mention of Memorial Day as a day of remembrance. In 2005, they featured a silhouette of a butler blowing a trumpet.
We also are celebrating in weather-appropriate skies (until it rains, at least) with red, white, and blue.
