Incubator
I’ve been playing around with a new application called Incubator by a company called MindCad. It is a pretty cool brainstorming application when you need to branch categories or categorize things. You just double click on the page to add an item, or command double click to add a topic. Then you can slide your items around and have them chain together. Below is a very simple example of how it connects topics and items in a hierarchy.
Incubator is a little bit pricey for what it does. It is $49.00. I wrote a suggestion to the company and got a nice message back from the developers. So that is a good sign that the money paid is probably going back into the product.
