From the shortest texts and tweets to the humblest website, to the angriest blog, to the most visited social networks, the daily communications of the wired world attest that everyone is now in the business of relentless self-promotion–presenting themselves, explaining themselves, defending themselves, selling themselves or sharing their inner thoughts and emotions as never before in human history. That is why it can be said that we are in the grand secular age of apologetics.— Os Guinness (cited in, Why we all need to be trained in Christian Apologetics)
