I've published a selection of over a thousand quotations that I have collected over the years, from the pre-Internet era to yesterday (I keep adding to the collection).
Accessing the Quotes
I used to have a nifty quote-of-the-day widget, and an iPhone app, and sub-pages here sorted by category, and all sorts of cool stuff. It all was powered by DabbleDB, which got acquired and killed. Oops.
Until I rebuild it in something else, here’s the raw list as a Google Doc. Sorry about the length.
