Chad Dickerson asks "is Wiki under your radar?" in his latest column at InfoWorld. Most of the column is about his exploration of Wikis and deciding which one to install at InfoWorld. The kicker, is that after all that, he finds that its already been installed months before. Some CIO's get nervous when that happens. I always say that "I love when good things happen and I didn't have to push it." Most IT people will scratch their itches and that's a good thing, in general. The trick is discovering these rogue projects and then finding ways to grow them into services that the rest of the organization can use.
