You should be able to catch a significant portion of my interpretation of this project from the following lists:
Advantages of the idea:
* Increases ease of political involvement advocacy.
* Allows those with knowledge/talent to multiply their efforts at writing quality letters.
* Encourages agenda-setting.
Disadvantages of the idea:
* Overly reliant on a crucial bit of yet cutting-edge technology: snail mail.
* Basically already accomplished.
* Increasing advocacy "noise" is likely to erode the impact of true homegrown letter-writing.
I envision an interface that integrates several fields of user-entered data (e.g., name, salutations, personal message) with one or more "boilerplate" paragraphs from a database of user-reviewed advocacy statements (addressing abortion, gay marriage, involuntary sterilization, etc.) and then allows the user to personalize the entire letter.
The software assists users in directing the letters to the relevant gatekeepers/politicians, then allows them to print off a double-sided page that is automatically addressed for being tri-folded and sent.
