I'm going to have to throw myself in the camp of those who don't have much interest in publishing a page or blog. I suspect that it would either be ignored or result in protestors setting up outside of my house.

If a strong urge to write presented itself, I rather like the idea of self-publishing either a novel or a non-fiction book on something I know a reasonable amount about. It not only would force a certain discipline to writing and study for the author, but would serve as my tiny push towards encourage long-form reading again as opposed to the modern urge to read things that fit on a computer screen (like I'm doing here of course).
