Do you ever need to sketch out a simple diagram? Nothing fancy, no Visio overkill, just a quick set of thoughts or actions connected and related to each other. Visualize your thoughts, map out a process, or build an easy "do this, then do that" list with the simple but "web 2.0 cool" mapping application Bubbl.us.
It's easy to use: Log in, type in the first box, hit enter, type in the next, etc. Here is a quick map I made for "How to prospect expired listings".
