I started writing this free task manager (http://abstractspoon.weebly.com/) in 2003 and it proved to be quite popular. I still work on it on a semi-daily basis because I enjoy it but users can be soooooo demanding. I've received some emails that I've allowed to spoil my day, and some people have tried to ride on my coat-tails but overall it's been a very rewarding experience and it kept me sane after my divorce. I wish you luck in your adventures.
