I am a frequent reader of David Sparks blog MacSparky. I found a link to a new piece of software by the folks at Literature and Latte (developers of Scrivener). Scrivener is a fantastic piece of software for writing and an essential tool in my writing productivity arsenal--I'll write about how I use it soon. Scrivener's new little brother is Scapple--a brainstorming application now in beta. Scapple allows you more flexibility in capturing and organizing your ideas than traditional mind mapping software.You can read about and download the Scapple beta here.
