Designer Macworld Part 3: OmniGroup
Omni were showing off their new OmniFocus application, for those who are fans of the GTD approach to task management.
They were also showing (in beta) version 5 of their oddly-named but wonderful application OmniGraffle. This is usually described as diagramming application similar to Visio, but this does its wide range of applications an injustice. I use OmniGraffle all the time for all manner of activities, from resource tracking to brainstorming to creating quick and dirty websites. At frog design (where Tim and I work), it is used by many folks for more traditional information design and taskflow analysis.
Version 5 fixes some of the small niggles from the previous rev, like how the automatic hierarchical tree building works (think org charts). But it also introduces new features like true beziers, improved master pages, a dramatically improved stencil management palette, and an overall streamlined interface that should make working in it significantly faster, especially if on a laptop (goodbye floating palettes).
Adam Richardson is the director of product strategy at Frog Design, where he guides strategy engagements for Frog's international roster of clients, envisioning and creating new products, consumer electronics, and digital experiences. Adam combines a background in industrial design, interaction design, and sociology, and he spends most of his time on convergent designs that combine hardware, software, service, brand, and retail. He writes and speaks extensively on design, business, culture, and technology, and he runs his own Richardsona blog. Adam is a member of the CNET Blog Network and is not an employee of CNET. 
If you have a mac you owe it to yourself to check out the omnigroup apps. OmniPlan is MS Project without the MS BS. Really great to use.
