That's interesting, the link worked ok for me.
I have found a new interface for brainstorming. It's called Linoit
It's sort of an online sticky board, where you can also include links and pictures. The nicest thing about is that the stickies can be loooong discourses of any length, or short little ideas. Of course, you'd want to reduce the size of pics so that they don't take up your limited space, but text doesn't take up much room at all. If you run out of space, you can always sign up for more with another email address.
It has some nice features...You can make multiple boards public or private, inviting others to participate or merely look at what you've done. Go check it out...
Wheeeee! More playgrounds!!!
I agree - Linoit is my favorite so far - and because it's so easy to post from so many different platforms, I think it's the most accessible for brainstorming and collaboration.
