An anonymous reader writes "What's The Greatest Web Software Ever Written?, Charlie Babcock of InformationWeek asks, in his follow up to last year's widely read list of greatest software period. The winner then was BSD 4.3. The new Top 12 list is a little funky in that it doesn't distinguish between apps, sites, and controls — XMLHttpRequest object set — is one of the winners. It includes many of the usual suspects, like Digg and AIM, along with some unexpected winners. (like World of Warcraft) The number one choice however, Apache server, is arguably correct."
