Great for SEO possibly but confusing for type-ins. Blimps and airships are undergoing a revolution of change and currently enjoying a renaissance in development. See the article Return of the Airship in the October 2006 Popular Mechanics. (I'd often thought if I came into a bit of money I'd develop a small fleet for travel in the Midwestern US).
On the other hand, most aren't familiar with those extensions in a professional sense and less so the general public, so they need branding and development. Visio has TM issues so I'd let that one drop IMO. Bli.mp has some true potential developed, low xxx as is.
