Dogpile is the shit! (lol...play on words...but I prefer it over Google any day of the week)
Thank you for your note. We understand your interest in seeing a Memorial Day Google logo. If we were to commemorate this holiday, we'd want to express reverence; however, as Google's special logos tend to be lighthearted in nature, this would be a particularly challenging design. We wouldn't want to create a graphic that could be interpreted as disrespectful in any way.
We have a long list of holidays that we'd like to celebrate in the future. We have to balance this rotating calendar with the need to maintain the consistency of the Google homepage. We really appreciate your feedback regarding the Google logo, and please be assured that we're actively pursuing ways in which we can acknowledge Memorial Day and other such occasions in the future.
Regards,
The Google Team
