When you're freewheeling through ideas that you yourself have collated -- particularly when you'd long ago forgotten about them -- there's something about the experience that seems uncannily like freewheeling ...

Modern indexing software learns associations between individual words, by tracking the frequency with which words appear near each other. This can create almost lyri... See more
