Limnu there were a couple of similar tools suggested on the Free Technology for Teachers Facebook page. I also received a couple of requests for suggestions for other similar tools. Here are some of the other tools that you and your students can use to host online brainstorming sessions.

iBrainstorm is a free brainstorming application for the iPad and the iPhone. The app allows you to record brainstorming sessions using a combination of free hand drawings and sticky notes.

Padlet is an incredibly versatile tool with which you can do everything from sharing bookmarks to sharing sticky notes to running a microblog.

Last, but not least, Google Apps for Education provides a bunch of options for students to use to organize their thoughts. Students who prefer to illustrate their ideas can use Google Drawings to create a mind map then insert it into a Google Document. The commenting feature in Google Drawings and Documents makes it easy for team members to ask clarifying questions, make suggestions, and reply to questions and suggestions.
Applications for Education
Whether it is to solve a problem, plan a project, or develop new story ideas there are plenty of occasions in the course of a school year for students to brainstorm together. I still believe that nothing beats getting together in a room to swap ideas in person, but that's not always practical or possible. For those times when in-person brainstorming sessions are not possible, the tools featured above offer good ways to host brainstorming sessions online.
