Matthew J. McCullough, who is known as the "Trainer of everything Git" at GitHub, is enthusiastically expanding the range and frequency of Git training events and conferences. He highlights the popularity of these events, noting that many, like the Strange Loop in St. Louis and JavaZone in Norway, often sell out well in advance. Upcoming European workshops, including Software Architect in London and Øredev in Malmö, still have limited availability, inviting potential attendees to reserve their spots. McCullough expresses excitement about the growing opportunities to engage with participants through these educational sessions.
