Most of the previous comments tell a similar story: people resist to new technologies. Unfortunately, and slthough in a smaller (i. e., non-corporate) scale, my experience is the same: whenever a team needs some collaboration tool, instead of clogging e-mail boxes, I’m an evangelist for tools like GoogleDocs or Zoho. I’ve given up on telling people about wikis, but when they show an inner refusal of something that is just like the MSWord or MSExcel (minus featuritis) they keep using, it’s hard to understand. Maybe, as others have acknowledged, it’s really a communication (and team cohesion) problem; I like to think it will take some 5 years for these tools to be widely used — as it took for e-mail to become so ubiquitous —, but I’m losing my faith.
