I have a couple of quick questions about it...
First of all, what language would you be writing it in? PHP is easier for the user (sysadmin) to support, since it isn't compiled into a bytecode. Also, if it is written in PHP, I would probably want to help develop it as well, though I would probably not ask for any money for helping.
Second, what specific categories of personal development would you cover? You mentioned emotional mastery, i.e., managing fear, as an example in your original post... While that is a necessary part of the whole, it doesn't cover the overall topic of personal development. I don't believe that there is any one specific method for organizing all of the different elements that go into personal development, so a design consideration might be to set each individual topic up as a module that the end users can enable or disable for their specific accounts.
For example, one of the keys to defeating fear is to gain knowledge. One way that I can think of, programatically, is to have people put their fears in, then allow them to list things that they have learned about those fears, or to write down what they have done to face the fear directly. When a person feels that they have overcome their fear, they hit a button, and it gets archived.
This could also apply to overcoming pride, taking responsibility, and gaining unconditional love, if we wanted to start with the emotional mastery field first.
For the layout of a person's first page, it could be a good idea to copy Google's new personal page layout, as seen here:
Google
Tabbed pages would be something to program in a bit later, of course, but each content box would be able to show important, relevant information from the modules that the user has enabled, such as their top five fears, items from their daily task list, random long-term goals (or goals that they have set to a high priority), etc.
My last question is, how much do you think it would cost to get something like this built? Chances are, I won't be able to pay for it, but I would like to see this done, so if someone else around here could be a buyer...
