For the same reason you're asking YOUR question, Guava. Google does not know all. Besides, some questions stimulate debate and on-line conversation with other Answerbankers.
Also, some people are not very good spellers, find it hard to formulate search terms for Google, and/or have difficulty in picking out the most useful sites from the multiplicity of "hits" returned by Google.
Since Tommy suggested it above, if you click here, that will link you to a web-page which shows not just my answer to this same question when it appeared earlier, but the answers of several other AnswerBank people too.
