“Multi-platform, multi-media opportunities translate into multi-choices. Social media and the Internet, in general, have turned life into an interconnected open-book exam - a sharp and important difference from the closed-book-exam shape of traditional research. (via Warc).”

“Effective marketing is really quite simple: Identify your destination (goals). Determine how best to get there (strategy). Get started (tactics). Measure your progress (reporting and analysis). Make course corrections as needed (continuous improvement).”
