Most bookmarking tools — the ones built into web browsers, and bookmarklets for third-party apps — do use the page title as the default bookmark name. Tools that help people tweet links to articles use the page title as the default description. So make titles useful. Write them for humans, not search engine spiders.
I’ve never considered my page titles confusing or technically, nonhuman. To be honest though, I never considered the page title in the design of this website. That said, thanks to John Gruber this is not the case. I’ve opted for DF-styled titles for all links, articles and pages.
