When typing a search into Google, a drop-down box will appear and follow what you're typing with suggestions based on other searches that users have made or phrases which appear with frequency. Typing "pinstripe" will give such examples as "pinstripe tape", "pinstripe alley", "pinstripe suit", "pinstripe baseball pants", and even "pinstripe bible". Of course, because Google is used by every last person with an internet connection (give or take), including children, common curse words do not appear in any suggestions.
Koi Koi Eleven researchers* have come across a strange abnormality in this modus operandi; in addition to profanities, the word "manga" in all its forms is also absent. Entering "yotsuba" or "yotsubato", the name of a very popular Japanese comic, will give such results as "yotsuba online", "yotsuba read", "yotsubato raw", and "yotsubato scanlation", which all hint at manga in different forms. Even "yotsuba anime" is present, even though there are no plans for producing an animated version of the series. Neither "yotsuba manga" nor "yotsubato manga" ever appear.
The creator of the Yotsubato! franchise is Kiyohiko Azuma, whose other wildly popular work is Azumanga Daioh. As you can see, the word "manga" is built right into the name. Because of this, the word "azumanga" never appears in any Google suggestions. The same goes for "manganese", an element of the periodic table.
Google reserves the right to censor out any words it wishes, but why "manga"? What is the logic behind this? And what other words are secretly verboten by Google Suggest? An explanation from Google would be welcome in this matter.
