The writer Jason Kottke, ten years ago on why he writes his all-encompassing blog:
A friend of mine says, “Nostalgia is death,” but I hope my approach is more than pining for the olden days of weblogs. Kottke.org is a way for me to relate to the world as a whole person, communicate with like minds, celebrate knowledge, and, yes, to write my own personal World Book.
The last two resonated strongly with me. The intersection between myself and the world is a tiny fraction of a percent of the world. And what I write is a tiny fraction of a percent of that. That infinitesimally tiny experience of the world, communicated through this site, is (to me) incredibly rich.
