Rob Fahrni’s project to get Visio rendering OPML files into diagrams reminds me why I don’t use Visio when I’m doing sitemap work for Web sites. Instead, I use a product called Inspiration. The main reason for this is that Inspiration has a built in outliner that lets you define hierarchical relationships and do all your typing outside of the actual diagram mode. This makes the labor intensive process of defining sitemaps for large sites that have more than 200 pages quite a bit easier.
I’m curious what tools other people use for this sitemapping/information design part of the Web site building process. I believe that I discovered Inspiration via one of Kelly Goto’s talks at a Web Design conference I attended in Atlanta. What do you use?
