Have you ever thought about how many keynote speakers are actually introverts? Think about the distance on the stage from the audience - even when you have an engaging speaker who includes the audience. Then think about podcasting and the intimacy of podcasting. You are putting the show in your ears - you are listening to them in your car, your home, while walking the dog. You build a personal relationship with the host and their guest.

I’ve been a speaker at events. I see the pluses, but I’ve also seen how limited the opportunity for that 3-5 day effort returned. The biggest benefit is strengthening the relationship with the organization that invited me to speak to its members. Most of my speaking is to private professional organizations, so nothing is recorded and definitely not published. Adding these events to my portfolio of speaking can be problematic as I usually speak on proprietary topics specific to the audience. I’ve also spoken on behalf of my non-profit to large ballrooms, and conferences. It made a memorable event, but rarely outside that event led to much more than a few compliments. Even when the carrot to speak at the event was access to the list, the attendees were rarely decision makers, so they would read the subject, and typically, that was that.

Here is a recent post on this topic comparing the effectiveness of both options.
