In order to celebrate the release of +GTG
0.3, let me show you an historical thing.
This is a screenshot of the closed tasks in my actual GTG, the GTG I use every day. You can spot the very first tasks ever entered in a GTG. Those are all GTG related.
The very first task not GTG related was "manger des frites" (eating french fries) but it might have been a joke or a test.
The second task not related to GTG is a very serious one. You can spot it in yellow (color of my "@blog" tag) and is about posting how Home is Desktop is a good idea. The post can still be read here : http://ploum.net/post/201-the-aristocratic-desktop-part-2-home-is-desktop
It's incredible how going through your completed tasks is a bit like time-travelling. It's part of the history.
I'm glad that GTG doesn't remove tasks and allows you to have a glance on what was your life then :-)
