title: Remembering a quote from Alan Kay
body: <p>Alan Kay was quoted several years ago to the effect that there had been only three new things in software in the preceding 20 years (effectively the lifespan of PCs). One of them was Spreadsheets.</p>
  
  <p>Does anyone remember the other two?</p>
  
  <p>Who is Alan Kay? (a few may ask.) His work at Xerox Parc arguably did more to shape our current software paradigm than any other influence.</p>
