Search Engines Web tells us that Ward Cunningham, who created the Wiki concept more than ten years ago, is (surprise, surprise) an advocate of collaboration and publicly available information. The article cited includes a lot of background on where the concept came from, but in amongst the buzzwords like "agile development" might be a message for libraries about patron expectations in the future.
"I'm betting on open source being a big trend," Cunningham said, chuckling at his understatement. "And it's not just because of cost, but because of end-user innovation. No end user wants to be a programmer; they just want to get their jobs done," he said. But more and more people with powerful tools and powerful languages will be able to work together to build better systems, he said.
