Excel is also the Mother of all list-making apps. From Spolsky (May 2000):<p>&gt; <i>When we were designing Excel 5.0, the first major release to use serious activity-based planning, we only had to watch about five customers using the product before we realized that an enormous number of people just use Excel to keep lists. They are not entering any formulas or doing any calculation at all! We hadn&#x27;t even considered this before. Keeping lists turned out to be far more popular than any other activity with Excel. And this led us to invent a whole slew of features that make it easier to keep lists: easier sorting, automatic data entry, the AutoFilter feature which helps you see a slice of your list, and multi-user features which let several people work on the same list at the same time while Excel automatically reconciles everything.</i><p><a href="http:&#x2F;&#x2F;www.joelonsoftware.com&#x2F;uibook&#x2F;chapters&#x2F;fog0000000065.html" rel="nofollow">http:&#x2F;&#x2F;www.joelonsoftware.com&#x2F;uibook&#x2F;chapters&#x2F;fog0000000065....</a>
